scsi: ufs-qcom: resume ICE driver after clock ungating

Browse source 
UFS core driver may power collapse the UFS host controller during clock
gating hence we might loose some of the ICE register configuration.
In order to restore ICE register configuration, we should call ICE
driver's resume callback after ungating UFS clocks.
