We fill postreset with ata_std_postreset() at sas_sata_ops before, but we
found out that ata_std_postreset() call sata_scr_read()/sata_scr_write()
which need to access SCR register. Actually we don't own these kind of
register, so sata_scr_read()/sata_scr_write always return -EOPNOTSUPP.
We drop ata_std_postreset() at sas_sata_ops.
