The Prestera range covers a lot of different silicon. 98DX326x appears
to be AlleyCat3; does this driver definitely support all previous
revisions too? I've started looking at some 98DX4122 (BobCat+) hardware
and while some of the register mappings seem to match up it looks like
the DSA tagging has some extra information at least.
Worth making it clear exactly what this driver is expected to support,
and possibly fix up the naming/device tree compatibles as a result.
