[PATCH v1 09/10] ufs: host: mediatek: Change reset sequence for improved stability

[peter.wang at mediatek.com]

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

This patch modifies the reset sequence to ensure that the device
reset pin is set low before the host is disabled. This change
enhances the stability of the reset process by ensuring the
correct order of operations.
