Subject: [PATCH v8 24/27] drm/vc4: tests: Remove vc4_dummy_plane structure

The vc4_dummy_plane structure was introduced as a mean to add
mock-specific fields.

However, we never really used it and it's still strictly equivalent to
vc4_plane (which is in the same situation vs drm_plane), so we can
simply remove the vc4_dummy_plane structure and make the mock code
cleaner.
