cpu/samd21: configure GCLK4 with 1024 Hz
...
Both WDT and RTC expect a 1 kHz clock.
Source it from the same generator as the 32 kHz GCLK2.

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/samd21: allow to use XOSC32K for GCLK2
...
GCLK2 is needed by RTC/RTT, so make it possible to configure it with
XOSC32K as source.

...
Notice that RIOT was using FDPLL96M, which is indeed the name in the
datasheet. But Atmel is using GCLK_GENCTRL_SRC_FDPLL.
