Public bug reported:
[Impact]
Under certain conditions, the SAS controller may not recover from an STP link
timeout, which can make disks behind the controller inaccessible.
[Test Case]
I don't have a way of injecting this error, so regression tested only.
[Fix]

scsi: hisi_sas: Fix the failure of recovering PHY from STP link
timeout
[Regression Risk]
This driver in Ubuntu is only used by the SoC in the D06 board, which will be
directly regression tested.
