[Intel-gfx] [PATCH v2 4/6] drm/vc4: vc4 driver changes to accommodate changes done in drm_writeback_connector structure

[Kandpal Suraj]

Changing vc4 driver to accomadate the change of
drm_writeback_connector.base and drm_writeback_connector.encoder
to a pointer the reason for which is explained in the
Patch(drm: add writeback pointers to drm_connector).
