scsi: hisi_sas: Update disk locked timeout to 7 seconds

The SATA disk will be locked after the disk sends the DMA Setup frame
until all data frame transmission is completed. The
CFG_ICT_TIMER_STEP_TRSH register is used for sata disk to configure the
step size of the timer which records the time when the disk is
locked. The unit is 1us and the default step size is 150ms. If the disk
is locked for more than 7 timer steps, the io to be sent to the disk
will end abnormally.

The current timeout is only about 1 second, it is easy to trigger IO
abnormal end when the SATA hard disk returns data slowly. Adjust the
timeout to 7 seconds based on ERC time of most disks.
