cpu/sam0: refactor ADC_0 into plain ADC
...
This change is for all boards with a sam0 cpu. This cpu just has one ADC.
It is unnecessary to have defines with ADC_0_ prefix as if multiple ADCs
are possible.
Some defines were not used, such as ADC_0_EN, ADC_0_CHANNELS,
ADC_MAX_CHANNELS, ADC_0_CLK_SOURCE, ADC_0_CHANNELS
Change all ADC_0_ prefixes to ADC_

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.

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.

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.

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.

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
