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: use GCLK ID instead of bitmask
...
To simplify board definitions and for unification between samd2x and
newer models, don't use the GCLK bitmask in board definitions.
Instead use the GCLK index and generate the bitmask when needed.

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.

cpu/sam0_common/i2c: fix ambiguous reg assignment
...
The value assigned to the register was unclear due to usage
of bit-comparison and ternary operator, added parentheses to
make it explicit.
