scsi: hisi_sas: Enable force phy when SATA disk directly connected



[ Upstream commit 8aa580cd ]

when a SATA disk is directly connected the SAS controller determines the
disk to which I/Os are delivered based on the port ID in the DQ entry.

When many phys are disconnected and reconnect, the port ID of phys were
changed and used by other link, resulting in I/O being sent to incorrect
disk. Data inconsistency on the SATA disk may occur during I/O retries
using the old port ID. So enable force phy, then force the command to be
executed in a certain phy, and if the actual phy ID of the port does not
match the phy configured in the command, the chip will stop delivering the
I/O to disk.
