scsi: ufs: enable auto hibern8 only after device initialization 



Make sure auto hibern8 is enabled only after both host controller
and device initialization is complete. Enabling it before device
initialization could cause issues as the device might not be ready
to handle hibern8 enter/exit before initialization.
