cpu/sam0_common/gpio: don't hard-code number of ports

b1724a7d1b periph/rtc: normalize struct tm before usage 
A naive implementation may set a RTC alarm in 30s by calling

	struct tm now;
	rtc_get_time(&now);
	now.tm_sec += 30;
	rtc_set_alarm(&now, _cb, NULL);

This works for RTC implementations that use a RTT internally and call
mktime() to convert the struct tm to a unix timestamp, as mktime() will
normalize the struct in the process.

Call rtc_tm_normalize() when the RTC uses separate registers for time / date
components to ensure it is normalized.

This also modifies tests/periph_rtc to exercise this case.

f7279c84bb cpu/sam0_common: rtt: correcly clear flags. 
The INTFLAGS register is cleared by writing a 1 to the corresponding interrupt
flag bit. From the samr21's manual:

> Writing a zero to this bit has no effect.
> Writing a one to this bit clears the Compare 0 interrupt flag.

This is a common pattern in flag registers.

This RTT driver is using or-equal to clear the flags, which means it can
possibly clear other interrupts. There's a small chance that one event is
missed if it happens very close to another event.

Credits to @benpicco, @dylad for pointing out missing fixes.

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.

f36d54f239 sam0/timer: various fixes 
This cleans up the sam0 timer driver:

 - remove the check for the unused freq parameter
 - the MCU provides dedicated SET/CLR registers to avoid
   read-modify-write, so don't do read-modify-write on them.
 - workaround a possible hardware bug on SAMD5x:
   loop until the CMD_READSYNC is really set

849dd4cdce sam0_common: make Timer implementation common across all sam0 MCUs 
The currently supported SAM0 MCUs (samd21, saml21, saml1x) share the same
Timer peripheral, yet each of them carries it's own copy of the Timer
driver.

This introduces a new timer driver that is common for all sam0 MCUs and
uses structs for configuration instead of defines.
