[PATCH] scsi: ufs-mediatek: Modify the minimum RX/TX lane count to 2

[Stanley Chu]

From: Andy Teng <andy.teng at mediatek.com>

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.
