cpu/esp32: small fix of rtc_init for light sleep
...
`rtc_init` is used after light sleep to update the system time from RTC timer. The fix corrects a small difference of about 230 ms which would sum up with each wakeup from light sleep.

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.

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

We have to read the DR for every byte that we write.
Just reading DR while SPI is busy in a loop can lead to bytes being
