drm/bridge: it6505: Fix the order of DP_SET_POWER commands
...
Send DP_SET_POWER_D3 command to the downstream before stopping DP, so the
suspend process will not be interrupted by the HPD interrupt. Also modify
the order in .atomic_enable callback to make the callbacks symmetric.

Rename dp/ to display/ to account for additional display-related
helpers, such as HDMI. Update all related include statements. No

Various drivers, such as i915 and amdgpu, use similar naming scheme
by putting code for video-output standards into a local display/
directory. The new directory's name is aligned with this convention.
