[PATCH v1 08/10] ufs: host: mediatek: Fix UniPro setting for MT6989

[peter.wang at mediatek.com]

From: Peter Wang <peter.wang at mediatek.com>

This patch sets the UniPro attribute 0xD09E[4] bit to enable the
1144 functions specifically for the MT6989 platform. This
adjustment ensures proper functionality and compatibility
with the MT6989 hardware.
