cpu/esp_comomon: rename cpu_conf.h to cpu_conf_common.h

To be able to define common configurations for all ESP CPUs, the CPU specific configuration cpu_conf.h has to include a common configuration. For that purpose cpu_conf.h in cpu/esp_common is renamed to cpu_conf_common.h and included in CPU specific configurations.

cpu/samd21: default 1kHz clock to same source as 32kHz clock
...
The split between GEN2_ULP32K and GEN3_ULP32K was introduced to fix
a failure in tests/periph_wdt when the external oscillator was used.
By not running the external oscillator on demand, the failure can no
longer be observed, so default GEN3_ULP32K to GEN2_ULP32K.

cpu/lpc2387: implement periph/i2c
...
The lpc23xx MCU has up to three I2C interfaces.
This adds a driver for it.
The peripheral works in interrupt mode, each change of the state machine
will generate an interrupt.
The response to the states are laid out in the data sheet.
This replaces the old driver that was removed in c560e28eb6

cpu/sam0_common: use generic exti_config
...
Creating an `exti_config` array for a new MCU manually is tedious and error prone.
Luckiely all information is already availiable in the vendor files.
Credit for this discovery & method goes to @Sizurka
The file was generated with
```C
int main(void) {
puts("static const int8_t exti_config[PORT_GROUPS][32] = {");
for (unsigned port = 1; port < 5; ++port) {
printf("#if PORT_GROUPS >= %d\n{\n", port);
for (unsigned pin = 0; pin < 32; ++pin) {
printf("#ifdef PIN_P%c%02uA_EIC_EXTINT_NUM\n", '@' + port, pin);
printf(" PIN_P%c%02uA_EIC_EXTINT_NUM,\n", '@' + port, pin);
printf("#else\n -1,\n#endif\n");
}
printf("},\n#endif\n\n");
}
puts("};");
return 0;
}
```
No changes in generated code are expected, but this makes adding new members
of the sam0 CPU families much easier.

cpu/lpc2387: clear BODR if POR is set
...
From the data sheet:
> **Note:** Only in case when a reset occurs and the POR = 0, the BODR bit
indicates if the V DD(DCDC)(3V3) voltage was below 2.6 V or not.
So the value of BODR is undefined if POR is set.
Clear it to bring it to a defined state.

cpu/lpc2387: rename cpu_woke_from_backup()
...
The function would always return `true` after early boot, so it
is not very useful for applications.
Now it will only (but always) return true when we woke from Deep Sleep
*after* early boot. This makes it behave the same ways as the function
of the same name on SAME54.
Rename the existing function to cpu_backup_ram_is_initialized() to better
match it's semantics.

cpu/lpc2387: rtc: only initialize RTC after cold boot or external reset
...
On the MCB2388 plugging the power will result in both the POR and EXTR
bit being set.
Not sure if this is a property of the board, but it means RTC is also
reset after programming, so it behaves just like Backup RAM.
If we woke from Deep Sleep the POR bit will be cleared, so the RTC is not
reset.

cpu/lpc2387: clear POR bit if we woke from Deep Sleep
...
RSIR is 0x1 (POR) if we woke from Deep Sleep.
This makes it hard to distinguish between real power-on and waking from
Deep Sleep, which is why the Backup RAM signature was introduced.
However, calling cpu_woke_from_backup() a second time will always return
true, as the signature will have been set up by early boot then.
Thus, clear the POR bit if the signature was already in place.
The result is:
RSIR == 0 -> woke from sleep
RSIR == 1 -> cold boot

cpu/atmega_common: Fix pm_reboot with LTO
...
The reboot process for ATmegas is to enable the watchdog timer and loop until
the wdt reboots this MCU. However, this reboot will keep the wdt configuration,
so that the wdt needs to be disabled during boot. This is done in get_mcusr,
but without the attribute "used" it will be optimized out in LTO builds. This
commits adds the attribute "used" to get_mcusr.
Also simplified the backward compatibility with older ATmegas (currently not
supported by RIOT) on outdated versions of avrlibc.

cpu/sam0: don't hard-code peripheral clocks
...
Instead of hard-coding the peripheral clocks to CLOCK_CORECLOCK
introduce helper functions to return the frequency of the individual
GCLKs and use those for baud-rate calculations.
This requires the GCLK to be part of the peripheral's config struct.
While this is already the case for most peripherals, this also adds
it for those where it wasn't used before.
As it defaults to 0 (CLOCK_CORECLOCK) no change is to be expected.

- Documentation was updated.
- The `cc1312-launchpad` board that uses the `cc13x2` MCU was updated.
- The `cc1352-launchpad` board that uses the `cc13x2` MCU was updated.

...
With the new toolchain version required to fix issue #13133 , the compilation of `examples/posix_socket` fails due to a C linkage error in `atomic_base.h`. The reason is that including `drivers/include/mtd.h` in `boards/esp32/board_common.h` inside the `extern C` block finally leads to including `atomic_base.h` inside the `extern C` block which in turn to the C linkage error for the template definitions in this file.

cpu/atmega_common/periph/uart: use TX_ISR to check TX end
...
For atmega boards a TX has not actually completed until UDRn is empty
as well as the Transmit Shift Register.
To avoid resetting an UART before a TX has completed we use the TXCn
flash and ISR to set a variables that indicates TX is ongoing. This
allows not reseting the UART while there are ongoing TX pending.
This fixes an issue where part of the last byte is not shifted out
of the TX shift register causing rubish on the first TX following an
uart_init.

cpu/efm32: fix incorrect ADC status register
...
The ADC_STATUS_SINGLEACT indicates that an operation is active, while
the ADC_STATUS_SINGLEDV indicates that data is valid.
This fixes ADC returning values of unfinished reads.

Without this change a RIOT application compiled with all-asan will
segfault as RIOT provides its own malloc by default. Add a define for
disabling custom malloc, calloc and realloc implementations and use it
when compiling with all-asan.

cpu/esp32: activate automatic XTAL detection

ESP32 can be clocked with either a 40 MHz or 26 MHz crystal. Since most boards use a 40 MHz crystal, the configuration was previously fixed to a 40 MHz crystal. This commit changes the crystal from 40 MHz to automatic detection, allowing boards with a 26 MHz crystal like the Sparkfun ESP32 Thing DEV to be used.

cpu/esp32: fixes and cleanups of RTC timer
...
- Unecessary definitions are removed.
- Since the 48-bit RTC hardware timer uses a RC oscillator as clock, it is pretty inaccurate and leads to a RTC time deviation of up to 3 seconds per minute. Therefore, a calibration during the boot time determines a correction factor for the 48-bit RTC hardware timer. Function _rtc_time_to_us uses now this correction factor and converts a raw 48-bit RTC time to a corrected time in microseconds. Thus, the 48-bit RTC timer becomes much more accurate, but it can't still reach the accuracy of the PLL driven 64-bit system timer. The Advantage of using RTC over 64-bit sydtem timer is that it also continues in deep sleep mode and after software reset.
- If the 64-bit system timer is used to emulate the RTC timer, it uses the RTC hardware timer to continue its operation after software .

cpu/esp32: introduce pseudomodule esp_rtc_timer
...
It is possible to use different timers as RTC timer for the periph_rtc module. Either the 48-bit RTC hardware timer is used directly or the PLL driven 64-bit system timer emulates a RTC timer. The latter one is much more accurate. Pseudomodule esp_rtc_timer controlls which timer is used. Only if esp_rtc_timer is enabled explicitly, the 48-bit RTC hardware timer is used. Otherwise the 64-bit sytstem timer is used to emulate the RTC timer.

cpu/esp32: system_get_time_ms cleanup

There is an existing function that returns the system time in us as a 64 bit value. Converting this 64 value in us to a 32 bit value in ms is more easier and uses the complete 32 bit range. Using only the low part of the 64 bit system time in us and dividing it by 1e3 cuts the 32 bit range.
