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. Signed-off-by: Tejun Heo <htejun@gmail.com>
