We are talking about creating a dummy device because:
- we need to give something for drm_platform_init(),
- drm related data should be stored somewhere,
- some data must be passed to all driver probe() functions. This is not
hw-related data, but just some lists that are used to ensure that all
drivers have been initialised before calling drm_platform_init().
All these issues are purely tegra-drm related and solving them elsewhere
(in host1x) would be just wrong! host1x would not even use the dummy
device for anything so creating it there seems bizarre.
