scsi: ufs-qcom: do clock gating and hibern8 @10ms

This change enables the aggressive clock gating along with hibern8 at
every 10ms. As hibern8 enter was already @10ms, we are now merging it
with clock gating which will also be @10ms after this change. This change
is needed to save power for real life usecases.
