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()

sam0_common: make Timer implementation common across all sam0 MCUs
...
The currently supported SAM0 MCUs (samd21, saml21, saml1x) share the same
Timer peripheral, yet each of them carries it's own copy of the Timer
driver.
This introduces a new timer driver that is common for all sam0 MCUs and
uses structs for configuration instead of defines.

cpu/samd21: Avoid clearing interrupt bits unintentionally
...
The INTENSET, INTENCLR, INTFLAG registers are write-1-to-confirm
registers, so writing zeroes will not affect anything, on the other
hand, a compiler generated read-modify-write cycle may unintentionally
affect more bits than the one being set. Avoid by using direct
assignment instead of or-assignment (|=) or bitfield writes (.bit.xxx=).
