drm/sun4i: hdmi: Remove duplicate cleanup calls
When the HDMI unbinds drm_connector_cleanup() and drm_encoder_cleanup() are called. This also happens when the connector and the encoder are destroyed. This double call triggers a NULL pointer exception. The patch fixes this by removing the cleanup calls in the unbind function.
