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/sam0_common/periph/uart: implement buffered write
...
Implement interrupt based uart_write() using a tsrb for the TX buffer.
To enable it, add
USEMODULE += periph_uart_nonblocking
to your Makefile.

cpu/sam0_common: uart: fix baud rate calculation
...
In fractional mode, 3 bits are used to store the fractional part.
Therefore we must multiply / divide by 8 instead of 10 in order to
get the correct values.

cpu/samd5x: add support for samd5x/same5x MCUs
...
This adds supoprt for the Atmel SAMD51 & SAME54 SoC.
The SAME5x/SAMD5x is a line of Cortex-M4F MCUs that share peripherals
with the samd2x Cortex-M0+ and saml1x Cortex-M23 parts.
