Jason-JH Lin afcfb6c847 drm/mediatek: Add pm_runtime support for GCE power control 
Call pm_runtime_resume_and_get() before accessing GCE hardware in
mbox_send_message(), and invoke pm_runtime_put_autosuspend() in the
cmdq callback to release the PM reference and start autosuspend for
GCE. This ensures correct power management for the GCE device.

Fixes: 8afe816b0c ("mailbox: mtk-cmdq-mailbox: Implement Runtime PM with autosuspend")
