scsi: ufs: fix the downdifferntial value for clock scaling

"downdifferntial" parameter of devfreq ondemand governor should
be set to value such that if the load is under upthreshold minus
downdifferential, the governor may consider slowing the frequency down.

As the devfreq ondemand governor is now fixed to handle the
downdifferential correctly, update the downdifferential parameter for
UFS clock scaling (which uses the devfreq ondemand governor).
