scsi: dt-bindings: mediatek,ufs: Add ufs-disable-mcq flag for UFS host

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.
