sam0/rtc_rtt: don't block until set_alarm has been propagated to periph
...
rtc_set_alarm() / rtt_set_alarm() are heavily used by ztimer during ISR. This will reduce time spent during ISR drastically. We trust that the peripheral is able to propagate the alarm asynchronously.

cpu/sam0/rtc: remove overflow IRQ
...
Due to the RIOT_EPOCH of 2020 this overflow will happen in year 2084. It would be scary if IoT devices are still around then.
We can save RAM and ROM. Furthermore, this overflow handling should block BACKUP power mode in order to keep track of the reference year.

cpu/sam0_common: RTC: wait for syncbusy in rtc_get_time()
...
`rtt_get_counter()` already waits for syncbusy before reading the time,
but we also have to do this in RTC mode (`rtc_get_time()`) to avoid
reading old values.
Thus, always wait for syncbusy to clear when accessing the COUNT register.

On SAM L21 only 8 EXTWAKE pins can wake the CPU from Backup sleep.
Handle this analogous to the RTC tamper pins on SAM D5x/E5x where
configuring them as an interrupt will also cause them to wake the
device from Deep Sleep.

cpu/sam0_common: SPI: don't perform DMA transfer for small buffers
...
Setting up a DMA transfer can take longer than sending out a buffer
byte by byte if the buffer is small.
DMA only shows advantages for large buffers, using it for every transfer
will cause a net slowdown.
Since we did not come up with a good way to determine the treshold based
on the SPI frequency, just use a fixed buffer for now so that DMA can be
used without slowing things down overall.

cpu/sam0_common: uart: set oversampling based on baud rate
...
In Asynchronous Fractional baud rate mode, the baud rate can not be
greater than the source frequency divided by the oversampling (8, 16).
Currently we are always using 16x oversampling.
This makes it impossible to e.g. set a 2 MHz UART baud rate on the 16 MHz
`saml10-xpro`.
With this change, the oversampling is automatically reduced to 8x which
allows us to set 16 MHz / 8 -> 2 MHz baud rate.
