sam0/adc: work around ADC errata on SAM D5x/E5x
...
The ADC SYNCBUSY.SWTRIG gets stuck to '1' after wake-up from Standby Sleep mode.
Ignore the ADC `SYNCBUSY.SWTRIG` status bit, this functionality is not used by
the driver anyway.

cpu/sam0_common: RTC: add timeout to spurious tamper event
...
Errate 2.17.4 says:
> Upon enabling the RTC tamper detection feature, a false tamper
> detection *can* be reported by the RTC.
It turns out that this spurious event is not always generated.
If RTC alarm is used and the CPU was previously woken from hibernate
by RTC, it *can* happen that the false tamper event is *not* generated.
In this case, we will block indefinitely on the mutex.
To solve this, add a timeout to the event.
Also poll the event instead of using a mutex, as we have already set
`PM->SLEEPCFG.bit.SLEEPMODE` at this point.

cpu/sam0_common: DAC: wait for DAC to be ready
...
The DAC can have some start-up delay.
If we try to write to it before it's ready, it will get stuck.
This happens now that `tests/driver_dac_dds` immediately sets a DAC
value after init.
The samd2x class of MCUs doesn't have this bit, but a quick test on
samd10 shows that it might not be nececary there - the DAC does not
get stuck when writing to it immediately after init.

`flashpage_write_raw()` got renamed to `flashpage_write()`.
Now `sam0_flashpage_aux_write_raw()` is the only remaining 'raw'
function, even though it behaves just like `flashpage_write()`.
So let's also rename that for consistency.

cpu/sam0_common: GPIO: use tamper detection to wake from Deep Sleep
...
On samd5x only the RTC can wake the CPU from Deep Sleep (pm modes 0 & 1).
The external interrupt controller is disabled, but we can use the tamper
detection of the RTC.
If an gpio interrupt is configured on one of the five tamper detect pins,
those can be used to wake the CPU from Deep Sleep / Hibernate.

sam0_common: Use Single-cycle I/O Port for GPIO when available
...
The Cortex-m0 based ATSAM devices can use the Single-cycle I/O Port for
GPIO. This commit modifies the gpio_t type to use this port when
available. It is mapped back to the peripheral memory space for
configuration access. When it is not available, the _port_iobus() and
_port() functions behave identical, which is the case for the samd51.
