cpu/sam0_common: add cpu_pm_cb_enter()/leave()
...
This allows to implement needed work-arounds surrounding sleep on
a per-MCU basis.

cpu/sam0: don't hard-code peripheral clocks
...
Instead of hard-coding the peripheral clocks to CLOCK_CORECLOCK
introduce helper functions to return the frequency of the individual
GCLKs and use those for baud-rate calculations.
This requires the GCLK to be part of the peripheral's config struct.
While this is already the case for most peripherals, this also adds
it for those where it wasn't used before.
As it defaults to 0 (CLOCK_CORECLOCK) no change is to be expected.

cpu: Moved stdio_init() into cpu_init()
...
- Removed stdio_init() from newlib's _init(), as this is too late in the boot
process to allow DEBUG()ing during periph_init()
- Added stdio_init() to the various cpu_init() routines of the ARM CPUs just
before periph_init()

cpu: saml1x/saml21: reduce differences in cpu.c
...
The init code for both MCUs is so alike, but it diverged over time.
Re-order the code, so that it's the same on both families again.
