This implementation seems to be incorrect for 6390X, and maybe
others. I just picked a modern devices at random, and it is different,
so didn't check any other devices.  The 6390X uses bits 14 and 15, not
just bit 14.

So either you need to narrow down support to just those devices this
actually works for, or you need to add implementations for all
generations, via an op in mv88e6xxx_ops.
