drm/amd/display: Power down hw blocks on boot
[WHY]
On headless boot a DIG may be turned on by VBIOS on RN. This leads to
display_count being non-zero in hybrid graphics cases leading to SMU
DISPLAY_OFF message not being sent.
[HOW]
Power down hardware on boot
if seamless boot is not occurring
(power_down_display_on_boot == 1)
