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.
Micron and Skhynix UFS device needs DELAY_BEFORE_LPM quirk to have a
delay before VCC is powered off.
Toshiba UFS devices require delay after VCC power rail is turned-off
in QCOM platforms. Hence add Toshiba vendor ID and DELAY_AFTER_LPM
quirk for Toshiba UFS devices in QCOM platforms.
