scsi: ufs: exynos: Enable write line unique transactions on gs101

Currently just AXIDMA_RWDATA_BURST_LEN[3:0] field is set to 8 in
exynos_ufs_post_link() function.

To enable WLU transaction additionally we need to set Write Line Unique
enable [31], Write Line Unique Burst Length [30:27] and
AXIDMA_RWDATA_BURST_LEN[3:0].

To support WLU transaction on gs101, both burst length fields need to be
0x3. As all other SoCs expect the current value we update this in the
gs101_ufs_post_link() specific hook.
