[PATCH v3 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>

Correct the system resume flow by turning MTCMOS on before setting
LPM to false. During system suspend, set LPM to true and turn
MTCMOS off. Ensure proper power management and system stability
with the updated resume sequence.
