93d2068a9e cpu/atmega_common: Implement RTC based on TIM2 
This implements a basic Real Time Clock based on TIM2.

As the timer is too fast and wraps around after just 8 bits, it is
not used directly. Instead TIM2 is responsible for providing a 1 Hz
tick by generating an alarm every second.

The current time data is kept in the `.noinit` section, so it will survive
a reboot, but the clock will not be updated while the bootloader runs, so
expect inaccuracies.

0032d35fe8 cpu/sam0_common: mitigate rounding errors of baud rate calculation 
Instead of always rounding up, the driver now rounds to the nearest integer. This reduces the absolut rounding error when setting SPI baud rates.

1ca26adde8 cpu/esp32: rtc: use rtc_mktime() for Y2038k 
By using a custom EPOCH for the RTC implementation, we can extend the
range of the 32 bit counter based RTC by 118 years.

It also reduces the code size compared to the stdlib based POSIX functions.

ef248b392d cpu/esp_comomon: rename cpu_conf.h to cpu_conf_common.h

51fa5afef7 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.

937c954d92 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

b77afadb49 cpu/sam0_common/gpio: use explicit GCLK names 
For consistency, use named GCLKs.

 - `SAM0_GCLK_32KHZ` will always be 2 for samd21
 - `SAM0_GCLK_MAIN` will always be 0

So no change in functionality, just makes the code easier to understand.

fd9a247200 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.
