scsi: ufs: ufs-qcom: Add fixup_dev_quirks vops

Browse Source 
Add fixup_dev_quirk vops in QCOM UFS platforms and provide an initial
vendor-specific device quirk table to add UFS device specific quirks which
are enabled only for specified UFS devices.

 - Add DELAY_BEFORE_LPM quirk for Skhynix UFS devices to introduce a delay
   before VCC is powered off in QCOM platforms.

 - Add DELAY_AFTER_LPM quirk for Toshiba UFS devices to introduce a delay
   after the VCC power rail is turned off in QCOM platforms.

 - Move UFS_DEVICE_QUIRK_HOST_PA_TACTIVATE quirk from
   ufs_qcom_apply_dev_quirks to ufs_qcom_dev_fixups.
