Merge patch series "Enhance UFS Mediatek Driver"

Peter Wang <peter.wang@mediatek.com says>:

Improves the UFS Mediatek driver by correcting clock scaling with PM
QoS, and adjusting power management flows. It addresses
shutdown/suspend race conditions, and removes redundant
functions. Support for new platforms is added with the MMIO_OTSD_CTRL
register, and MT6991 performance is optimized with MRTT and random
improvements. These changes collectively enhance driver performance,
stability, and compatibility.

Changes since v1:

 1. Remove two patches that will be fixed in UFS core.
    - ufs: host: mediatek: Fix runtime suspend error deadlock
    - ufs: host: mediatek: Enable interrupts for MCQ mode
 2. Use hba->shutting_down instead of ufshcd_is_user_access_allowed
