cc26xx_cc13xx: add ROM Hard-API 
This is needed to switch the SCLK_HF source clock safely.

Note: these functions work on cc26x2_cc13x2 and cc26x0, but special care
needs to be taken when calling on cc26x0 some of these functions, as
ADDI_SEM needs to be taken.

bfb3d52a63 cpu/sam0_common: implement periph/dac 
The sam0 MCUs all have a DAC peripheral.
The DAC has a resulution of 10 or 12 bits and can have one or two
output channels.

The output pins are always hard-wired to PA2 for DAC0 and PA5 for DAC1
if it exists.

On the same54-xpro I would only get a max value of ~1V when using the
internal reference, so I configured it to use an external voltage reference.

The external reference pin is hard-wired to PA3, so you'll have to connect
that to 3.3V to get results.

cpu/stm32f1: dont provide periph_rtc at cpu level 
stm32f1 periph_rtc implementation gets a 1s resolution by dividing
CLOCK_LSx by 32768. This only make sense if CLOCK_LSE is set,
otherwise CLOCK_LSI=~40000, which will lead to an imprecise rtc.

c21b5d6f55 cpu/lpc2387: PM_NUM_MODES must only count non-idle modes 
lpc23xx has 3 sleep modes and one idle mode.
`PM_NUM_MODES` must only count the idle modes.

In practise, this makes no difference since `mode 3` (IDLE) is
the `default` case in `pm_set()` anyway.

The calculation of `_state_index` is broken for `port = 2`

Will not yield the right result. As a consequence, IRQs on Port 2
are not working.
The right thing here would be

    _gpio_isr_map[n + (port ? 32 : 0)];

But we might just re-using the `_isr_map_entry()` function.
Also only iterate as many times as there are set interrupt bits.

7e7b6e1cfe Allow to define reserved fields in CortexM vector table. 
The ARM CortexM vector table has some reserved fields which are used by
some manufacturers to store their custom image information. In
particular, NXP QN908X stores the checksum, Code Read Protection, image
type and boot block pointer in this region.

This patch allows the cpu and board modules to define the value of these
fields at build time by defining a macro.

4451765952 cpu/lpc2387: fix check for max number of timers 
The CPU has 4 hardware timers.
Configuration for all 4 timers exists, but the compile-time range
check has an off-by-one error, causing the last timer to remain
inaccessible.

cpu/cortexm_common: add irq sub-priorities 
This commit enables Cortex-M CPU interrupt sub-priorities
and allows the PendSV interrupt to have a priority different
from the default one.  Together these two preprocessor
defines can be used to have PendSV always run as the last interrupt
before returning from the interrupt stack back to the user space.

Running PendSV as the last interrupt before returning to the
user space is recommended by ARM, as it increases efficiency.
Furthermore, that change enhances stability a lot with the
new nRF52 SoftDevice support, currently being worked in
PR #9473.

This commit merely enables sub-priorities and a separate
PendSV priority to be used without changing the default
RIOT behaviour.

49fda3e900 cpu/samd5x: don't run DFLL on-demand 
The DFLL on samd5x has a hardware bug that requires a special
re-enabling sequence when it is disabled and then re-enabled again.

When running the clock on-demand, the hardware handles the disabling
and re-enabling so that sequence does not get executed.

To reproduce, run `tests/periph_uart` on `same54-xpro`.

Without this patch the test will get seemingly stuck on `sleep_test()`.
(In fact it keeps running, but the DFLL has the wrong frequency so the
UART baudrate is wrong).

In this test, on `same54-xpro` only UART0 is sourced from DFLL.
So if the UART is disabled the DFLL will be turned off as well.

5d123cbb22 cpu/sam0_common: distribute PM_NUM_MODES among siblings 
Also adapt the defines to the documentation

 - CPUs define up to 4 power modes (from zero, the lowest power mode,
   to PM_NUM_MODES-1, the highest)
 - >> there is an implicit extra idle mode (which has the number PM_NUM_MODES) <<

Previously on saml21 this would always generate pm_set(3) which is an illegal state.
Now pm_layered will correctly generate pm_set(2) for IDLE modes.

Idle power consumption dropped from 750µA to 368µA and wake-up from standby is also
possible. (Before it would just enter STANDBY again as the mode register was never
written with the illegal value.)

d12abe6a2b cpu/samd5x: disable RTC on init to prevent undefined RTC state 
When changing the clock configuration while the RTC is running, the
RTC may end up in an undefined state that leaves it unresponsive.

The RTC is not reset to stay persistent across reboots/hibernate, so
it will not be reset on init.
Instead, disable the RTC while configuring the clocks, rtc_init() will
take care of re-enabling it.

@dylad introduced this workaround for saml21, samd5x needs it too.

To reproduce, set the CLOCK_CORECLOCK of a samd5x board (e.g. same54-xpro)
to 48 MHz.
Run any RTC application. The CPU will be stuck in _wait_syncbusy() after
a reboot.
This patch will fix this. (You will need to power-cycle the board if the
RTC has entered the stuck state as it will never be reset.)

1505c105d2 cpu/esp32: allow WiFi modem sleep 
Due to stability reasons, the SoftAP interface of the WiFi module was always enabled in former versions even if only the station interface was used. Therefore the WiFi modem had to be always active and the SoC could not enter the modem sleep mode. Therefore, the SoftAP interface is only enabled when ESP-NOW is used.

4f977316fe cpu/esp_common: stop WiFi interface before sleep/reboot 
The WiFi interface should be stopped before reboot or sleep. But stopping the WiFi interface disconnects an existing connection. Usually, esp_wifi_netdev tries to reconnect on an disconnect event. However, trying reconnect with a stopped WiFi interface may lead to a crash. Therefore, the stop event has to be handled.

15ea6feeaf cpu/esp32: use hibernate mode for pm_off 
Now, where the vendor files for light/deep sleep mode are added, function `pm_off` does not need to implement this mode by itself. Instead the existing deep sleep with disabled wakeup sources is used for pm_off.

345827ce7b cpu/cc2538: gpio: save a few cycles in handle_isr() 
If only one it is set in state (one GPIO pin caused an interrupt),
don't loop over all 8 bits.

Use clz to get the position of the first interrupt bit and clear it,
looping only as many times as there are actual interrupts.
