I just saw that the two MFIS mailbox variants have a slight difference:
plain MFIS reg + 0: AP -> RT
plain MFIS reg + 4: RT -> AP
SCP MFIS reg + 0: SCP -> AP
SCP MFIS reg + 4: AP -> SCP
As this driver deals with the "AP" part, we need to access different
offsets when sending/receiving depending on which variant it is.
Shall we handle this with a different compatible?
