drm/amd/display: take dpms_off into account for edp turn off logic
[why]
Previously we incorrectly skipped backlight control when stream is
present but dpms_off = true. This causes backlight to remain on in
the we boot up or resume into a external display only configuration
where VBIOS posted on the eDP.
[How]
Add dpms_off into the condition for edp need to turn off.
