cc26xx_cc13xx: add RFC_DBELL/RFC_PWR definitions 
This definition is compatible with `cc26x0` and `cc26x2_cc13x2`.

The only difference is (cc26x0 -> cc26x2_cc13x2):

- IRQ13 -> FG_COMMAND_STARTED
- IRQ12 -> COMMAND_STARTED

Those IRQs aren't used on cc26x0 radio so it shouldn't affect anything.

59676a1f5e Make sure the mpu_noexec_ram regions has the lowest priority 
From the ARMv7-M ARM section B3.5.3:

	Where there is an overlap between two regions, the register with
	the highest region number takes priority.

We want to make sure the mpu_noexec_ram region has the lowest
priority to allow the mpu_stack_guard region to overwrite the first N
bytes of it.

This change fixes using mpu_noexec_ram and mpu_stack_guard together.

5d8c00e302 cpu/cc2538: implement periph/pm 
cc2538 implements 4 sleep modes.
In the lightest mode (3) any interrupt source can wake up the CPU.
In mode 2, only RTT, GPIO or USB may wake the CPU.
In mode 1 only RTT and GPIO can wake the CPU.
In mode 0 only GPIO can wake the CPU.

In mode 0 and 1 the lower 16k RAM are lost. This is a problem since those
are usually used by RIOT.

The linkerscripts in cc2538/ldscripts take different approaches towards that.
Some only use the upper 16k and leave the other half to be managed by the
application.

`cc2538sf53.ld` which is used by `openmote-b` uses the entire RAM starting
at the lower half, so it will not be able to wake up from those modes.

A quick fix to test those modes with `tests/periph_pm` would be

left in the fifo, corrupting subsequent reads.

  SWD debugging remains possible

nrf5x: Add built-in DC/DC converter enable function 
The internal DC/DC converter is more efficient compared to the LDO
regulator.  The downside of the DC/DC converter is that it requires an
external inductor to be present on the board. Enabling the DC/DC
converter is guarded with NRF5X_ENABLE_DCDC, this macro must be defined
if the DC/DC converter is to be enabled.

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.

202758f400 cpu/esp32/esp_wifi: changes for wpa_supplicant in WPA2 Enterprise mode 
`nvs_flash` functions have to be set to 0 if module `esp_idf_nvs_flash` is not enabled. Otherwise wpa_supplicant will crash in WPA2 Enterprise mode.

5b4389cf46 cpu/esp32: update of ld script for littlefs*
