I suppose we could just always ask for the extra soft-reset here (?)
Hmm... sata_mv doesn't do device classification, right? If so, it
should return -EAGAIN on success to tell EH to perform follow-up SRST.

Right now, mv_hardreset() is just a wrapper around sata_link_hardreset(),
and it just returns whatever it gets back from sata_link_hardreset().
And sata_link_hardreset() only returns -EAGAIN for hosts that support PMP.
Should sata_link_hardreset() instead always return -EAGAIN instead of 0 ?
Because that's essentially what we'd be doing by changing mv_hardreset()
to do that.

Mmm.. or maybe sata_mv should do what sata_std_hardreset() does:
rc = sata_link_hardreset(link, timing, deadline, &online, NULL);
return online ? -EAGAIN : rc;
Or, for that matter, perhaps sata_mv should just be calling sata_std_hardreset()
instead of sata_link_hardreset(). Those all got changed around at the same time
that I was working on sata_mv, so I might not have it quite right there (?).
