[PATCH v2 04/10] ufs: host: mediatek: Correct resume flow for LPM and MTCMOS

[peter.wang at mediatek.com]

From: Alice Chao <alice.chao at mediatek.com>

This patch corrects the system resume flow by ensuring that MTCMOS
is turned on before setting LPM to false.
During system suspend, LPM is set to true and MTCMOS is turned off.
The updated resume sequence ensures proper power management and
system stability.
