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.
