[v2,0/2] Enable HOST_PA_TACTIVATE quirk for WDC UFS devices

Message

Changes since v1:
- Instead of using this quirk for all Soc vendors, enable this quirk only for QCOM's platforms.

Western Digital UFS devices require host PA_TACTIVATE to be lower than
device PA_TACTIVATE, otherwise it may get stuck during hibern8 sequence.

Can Guo (2):
  scsi: ufs: Allow vendor apply device quirks in advance
  scsi: ufs-qcom: Apply QUIRK_HOST_TACTIVATE for WDC UFS devices

Applied to 5.7/scsi-queue, thank you!
