Benjamin Valentin 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.
