Some generic TV connector properties are exposed in drm_mode_config, but they are currently handled independently in each DRM encoder driver.
Extend the drm_connector_state to store TV related states, and modify the drm_atomic_connector_{set,get}_property() helpers to fill the connector state accordingly.
Each driver is then responsible for checking and applying the new config in its ->atomic_mode_{check,set}() operations.
