[PATCH v2 2/4] dt-bindings: ufs: mediatek,ufs: add ufs-disable-mcq flag for UFS host

[Macpaul Lin]

Add the 'mediatek,ufs-disable-mcq' property to the UFS device-tree
bindings. This flag corresponds to the UFS_MTK_CAP_DISABLE_MCQ host
capability recently introduced in the UFS host driver, allowing it
to disable the Multiple Circular Queue (MCQ) feature when present.
The binding schema has also been updated to resolve DTBS check errors.

Changes for v2:
 - Split new property from the origin patch.
 - Add dependency description. Since the code in ufs-mediatek.c
   has been backport to stable tree. The dt-bindings should be backport
   to the same stable tree as well.
