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.)

f6139ae346 cpu/samd5x: work around errata when (re-)initializing DFLL 
When a previously disabled DFLL gets enabled again, the frequency will
be incorrect. Follow the procedure outlined in the errata sheet, section 2.8.3
to work around the issue.

This fixes wake from standby.

Makefile.dep file.

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.

85b18a1c10 cpu/esp32: fix wake-up sources for sleep modes 
When entering a sleep mode, all wake-up sources should first be disabled before the wake-up sources required for the sleep mode are then stepwise enabled again. Otherwise, an wake-up configuration of one sleep mode may affect the wake-up within another sleep mode.

77961106f9 cpu/sam0_common: derive ROM_LEN, RAM_LEN from part number & vendor file 
The ROM size is encoded in the part number of the Atmel SAM chips.
RAM size is not encoded directly, so get it by parsing the chip's vendor file.

The file remains in the page cache for the compiler to use, so the overhead
should be minimal:

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.

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.
