scsi: ufs: ufs-pci: Fix hibernate state transition for Intel MTL-like host controllers

commit 4428ddea upstream.

UFSHCD core disables the UIC completion interrupt when issuing UIC
hibernation commands, and re-enables it afterwards if it was enabled to
start with, refer ufshcd_uic_pwr_ctrl(). For Intel MTL-like host
controllers, accessing the register to re-enable the interrupt disrupts
the state transition.

Use hibern8_notify variant operation to disable the interrupt during the
entire hibernation, thereby preventing the disruption.
