scsi: hisi_sas: workaround v2 hw SATA IO timeout issue
The v2 SAS controller needs more time to detect channel idle and send setup link request than SATA disk does, so it is difficult for the SAS controller to setup an STP link. Therefore it may cause some IO timeouts. We need to periodically configure the SAS controller so it doesn't receive STP setup requests from SATA disks for a while, so IO can be sent during this period.
