drm/amd/display: Send DISPLAY_OFF after power down on boot

Browse Source 
[WHY]
update_clocks might not be called on headless adapters. This means
DISPLAY_OFF may not be sent in headless cases.

[HOW]
If hardware is powered down on boot because it is headless (mode set
does not happen on that adapter) also send DISPLAY_OFF notification.
