From: Andy Teng <andy.teng@xxxxxxxxxxxx> MediaTek UFS host starts to support 2 lanes, thus modify the minimum 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.
