cpu/sam0_common: GPIO default to MAIN clock for EXTI, make configurable
...
Currently only samd21 used the 32 kHz clock for EXTI which makes it miss fast events.
All newer members of the family use the MAIN clock.
While touching this, also make the clock source configurable to this can be overwritten,
e.g. in the board config if desired.

cpu/sam0_common: gpio: Make use of dedicated GPIO interrupts
...
saml1x and samd5x have dedicated interrupts per GPIO line.
Use those instead of iterating over the GPIO status bits
to serve IRQs even faster.

Don't iterate over all bits in the GPIO status register, instead
just loop as many times as there are set bits.

cpu/sam0_common/gpio: use explicit GCLK names
...
For consistency, use named GCLKs.
- `SAM0_GCLK_32KHZ` will always be 2 for samd21
- `SAM0_GCLK_MAIN` will always be 0
So no change in functionality, just makes the code easier to understand.

cpu/sam0_common/gpio: don't hard-code number of ports
...
_exti() always assumes only 2 ports, so it will always fail when using
e.g. port C or port D on same54.
Instead, determine the number of ports from the dimensions of the exti_config
array.

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.
