scsi: ufs: ufs-mediatek: Modify the minimum RX/TX lane count to 2
MediaTek UFS host now supports 2 lanes. Modify the lane count to 2. This modification shall not impact old 1-lane host because PA_CONNECTEDRXDATALANES and PA_CONNECTEDTXDATALANES will limit the target lanes properly during power mode change. So we could relax the limitation in ufs_dev_params.
