39d71ac671 cpu/sam0_common: GPIO: ignore interrupts when interrupts are disabled 
If we disable an external interrupt, GPIO events that would generate an interrupt will still set the interrupt flag.
That means once we enable the interrupt again, a stale interrupt will be triggered.

This is surprising and probably not what the user wants, unfortunately the API documentation is not very clear about what to expect.
There is however no way to drop those intermediate interrupts with the current API.

Ignoring the events that occurred while the GPIO interrupt were disabled is probably the right (and expected) thing to.

c0203ad35c 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.

eb3f515f55 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.

6540609c35 cpu/sam0_common: gpio: save a few cycles in isr_eic() 
Don't iterate over all bits in the GPIO status register, instead
just loop as many times as there are set bits.

b77afadb49 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.

ba8dfc8341 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.

f375b00ff3 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.
