Mmm... I don't see how this helps.

The bulk of mv_sata_hardreset() is from sata_std_hardreset().

The only part those two do *not* have in common, is that
sata_mv needs to do it's own equivalent of sata_link_hardreset(),
so sata_link_hardreset() cannot be reused here.  Wrapper or not.

Now, if we had a per-LLD .link_hardreset op, defaulting to sata_link_hardreset,
then this would be trivial.
