Do we need the host1x_client/tegra_drm_client concept outside DRM? You
separated the two in an earlier patch, but the whole structure is there
because of limitation in DRM. Shouldn't we keep management of drm
clients entirely inside drm?

Second, do we need an own drm_bus for host1x clients? Does it bring
something drm_platform doesn't? I couldn't see any immediate difference
between the two.
