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