libata: move generic hardreset code from sata_sff_hardreset() to sata_link_hardreset()
sata_sff_hardreset() contains link readiness wait logic which isn't
SFF specific. Move that part into sata_link_hardreset(), which now
takes two more parameters - @online and @check_ready. Both are
optional. The former is out parameter for link onlineness after
reset. The latter is used to wait for link readiness after hardreset.
Users of sata_link_hardreset() is updated to use new funtionality and
ahci_hardreset() is updated to use sata_link_hardreset() instead of
sata_sff_hardreset(). This doesn't really cause any behavior change.
