Subject: [PATCH v4 0/8] scsi: ufs: support LU Dedicated buffer mode for WriteBooster

This patchset adds LU dedicated buffer mode support for WriteBooster.
In the meanwhile, enable WriteBooster capability on MediaTek UFS platforms.

v3 -> v4:
  - Introduce "fixup_dev_quirks" vops to allow vendors to fix and modify device quirks, and provide an initial vendor-specific device quirk table on MediaTek UFS platforms
  - Avoid relying on common device quirk table for pre-3.1 UFS device with non-standard WriteBooster support (Can Guo)
  - Fix comments for ufshcd_wb_probe() (Can Guo)
  - Make ufshcd_wb_get_flag_index() inline and fix ufshcd_is_wb_flags() (Avri Altman)

v2 -> v3:
  - Introduce a device quirk to support WriteBooster in pre-3.1 UFS devices (Avri Altman)
  - Fix WriteBooster related sysfs nodes. Now all WriteBooster related sysfs nodes are specifically mapped to the LUN with WriteBooster enabled in LU Dedicated buffer mode (Avri Altman)

v1 -> v2:
  - Change the definition name of WriteBooster buffer mode to correspond to specification (Bean Huo)
  - Add patch #5: "scsi: ufs: cleanup WriteBooster feature"

  scsi: ufs: enable WriteBooster on some pre-3.1 UFS devices
