da68386d9e drm: Rename dp/ to display/
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)

drm/bridge: tc358775: switch to devm_drm_of_get_bridge
The function "drm_of_find_panel_or_bridge" has been deprecated in
favor of "devm_drm_of_get_bridge".

Switch to the new function and reduce boilerplate.

drm/bridge: tc358775: Register and attach our DSI device at probe
In order to avoid any probe ordering issue, the best practice is to move
the secondary MIPI-DSI device registration and attachment to the
MIPI-DSI host at probe time. Let's do this.

drm/bridge: tc358775: Switch to devm MIPI-DSI helpers
Let's switch to the new devm MIPI-DSI function to register and attach
our secondary device. This also avoids leaking the device when we detach
the bridge.
