Hi,

This patchset adds LU dedicated buffer mode support for WriteBooster.

In the meanwhile, enable WriteBooster capability on MediaTek UFS platforms.

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"
