7269dc4e3a cpu/sam0_common: i2c: allow arbitrary I2C frequencies 
The Atmel I2C peripheral supports arbitrary I2C frequencies.
Since the `i2c_speed_t` enum just encodes the raw frequency values,
we can just use them in the peripheral definition.

We just have to remove the switch-case block that will generate an error
for values outside of `i2c_speed_t`.

cpu/sam0_common/rt%: issue READREQUEST to access CLOCK/COUNT regs 
read-synchronized register will stall immediatly when read, instead
issue READREQUEST and wait for sync to be unset.

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.

cpu/sam0: avoid deadlock on nonblocking write 
If a write to a full tsrb is attempted with disabled interrupts
or in a interrupt then a deadlock will occure. To avoid this make
space in the ringbuffer by synchronously writing to uart.

585dc15f99 cpu/sam0_common: UART: implement inverted RX & TX 
The UART TX and TX lines on SAMD5x and SAML1x can be inverted.
However, the flags don't do exactly what one would expect.

See errata 2.18.5: SERCOM-UART: TXINV and RXINV Bits Reference:

> The TXINV and RXINV bits in the CTRLA register have inverted functionality.
>
> Workaround:
> In software interpret the TXINV bit as a functionality of RXINV, and conversely,
> interpret the RXINV bit as a functionality of TXINV.

e93c9a82f1 cpu/sam0_common: RTC INTFLAG are clear on write 
Writing a 1 bit clears the interrupt flag, writing with |= is thus
uneccecary (and actually an error as this would clear *all* flags).

This cleanup was already done for rtt.c, but rtc.c missed out.
