For interrupt these are the valid onesÉ
- Common only
- TX and RX
- TX only
- RX only

The driver cuts this through by trying to request all and leaves it for
DT to specify the correct irqs.

Note: in case of common only, we still have RX+TX, TX only, RX only
operation, but that is just a side note.
