drm: Rename dp/ to display/

2022-04-25T09:17:45+00:00

Rename dp/ to display/ to account for additional display-related helpers, such as HDMI. Update all related include statements. No functional changes. 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. v2: * update commit message (Javier) Signed-off-by: Thomas Zimmermann Reviewed-by: Lyude Paul Reviewed-by: Javier Martinez Canillas Reviewed-by: Alex Deucher Link: https://patchwork.freedesktop.org/patch/msgid/20220421073108.19226-3-tzimmermann@suse.de
