the vc4_hdmi driver has some custom structures to hold the data it needs to
associate with the drm_encoder and drm_connector structures.

However, it allocates them separately from the vc4_hdmi structure which
makes it more complicated than it needs to be.

Move those structures to be contained by vc4_hdmi and update the code
accordingly.

Wait, does this patch build?  setting struct drm_encoder->base.type =
VC4_* seems very wrong, when previously we were setting struct
vc4_hdmi_encoder->base.type (struct vc4_encoder->type).

Other than this, patch 68-78 r-b.
