scsi: ufs: ufs-mediatek: Add UFSHCD_QUIRK_BROKEN_LSDBS_CAP
MT8183 implements the UFSHCI 2.1 spec but reports a bogus value of 1 in
the reserved part for the Legacy Single Doorbell Support (LSDBS)
capability.
Set UFSHCD_QUIRK_BROKEN_LSDBS_CAP when MCQ support is explicitly
disabled, allowing the device to be properly registered.
