Micron and Skhynix UFS device needs DELAY_BEFORE_LPM quirk to have a
delay before VCC is powered off. So add Micron and SKHYNIX vendors ID
and this quirk for both devices in QCOM platforms.

What makes these quirks specific for Qualcomm controllers? Are these
quirks perhaps required for all UFSHCI controllers?
