Sung Lee ca751df231 drm/amd/display: Power down hardware if set mode is not called before timeout

[WHY]
In headless systems, if set mode is not called, hardware will not be
powered down on boot, causing HW/SW discrepancies.  Powering down
hardware on boot will ensure SW state is accurate.

[HOW]
Set a timer callback on boot for 10 seconds. If set mode is not called
within that time, power down hardware. Otherwise, do not power down.
