scsi: ufs: ufs-qcom: Add support for reinitializing the UFS device
Starting from Qualcomm UFS version 4, the UFS device needs to be
reinitialized after switching to maximum gear by the UFS core. Hence, add
support for it by enabling the UFSHCD_QUIRK_REINIT_AFTER_MAX_GEAR_SWITCH
quirk, implementing reinit_notify() callback and using the agreed gear
speed for setting the PHY mode.
