vc4 driver currently embeds the drm_encoder into struct vc4_txp
and later on uses container_of to retrieve the vc4_txp from
the drm_encoder.
Make vc4 driver use the new API so that the embedded encoder model
can be retained in the driver and there is no change in
functionality.
changes in v5:
- reorder this change to come before in the series
to avoid incorrect sequence in subsequent changes
- continue using struct drm_encoder instead of
struct drm_encoder * and switch it in next change
