drm/amd/display: Power down hardware if timer not trigger
[WHY]
In headless systems, if SetMode/Power down timer
is not called, hardware will not be powered down
causing HW/SW discrepancies. Powering down hardware
on SetPowerState to D3 will ensure SW/HW state is accurate.
[HOW]
If PowerDownThread timer is not trigger but OS call
SetPowerState to D3, power down hardware.
