drm/vc4: Add DPI driver
The DPI interface involves taking a ton of our GPIOs to be used as
outputs, and routing display signals over them in parallel.
v2: Use display_info.bus_formats[] to replace our custom DT
properties.
v3: Rebase on V3D documentation changes.
v4: Fix rebase detritus from V3D documentation changes.
