Maybe what can be done is to just add a drivers/gpu/drm/core
subdirectory that would contain all the DRM core code ?

Then the dp helpers could be moved to drivers/gpu/drm/core/dp/drm_dp.c
for example. This would also make easy to differentiate the drm
modules from the drivers with just:

$ find drivers/gpu/drm -mindepth 1 -maxdepth 1 -type d -not -name core
