scsi: ufs: add delay before putting UFS rails in low power modes
We put the UFS device in sleep state & UFS link in hibern8 state during
runtime suspaned. After this we put all the UFS rails in low power
modes immediately but it seems some devices may still draw more than sleep
current from UFS rails (especially from VCCQ rail) atleast for 500us.
To avoid this situation, this change adds 2ms delay before putting these
UFS rails in LPM mode.
