[PATCH] libata: implement ata_drive_probe_reset()
Most low level drivers share supported reset/classify actions and
sequence. This patch implements ata_drive_probe_reset() which helps
constructing ->probe_reset from three component operations -
softreset, hardreset and postreset. This minimizes duplicate code and
yet allows flexibility if needed. The three component operations can
also be shared by EH later.
