[Intel-gfx] [PATCH 02/13] drm/i915: Convert intel_tv connector properties to atomic, v5.

As a proof of concept, first try to convert intel_tv, which is a rarely
used connector. It has 5 properties, tv format and 4 margins.
I'm less certain about the state behavior itself, should we pass a size
parameter to intel_connector_alloc instead, so duplicate_state
can be done globally if it can be blindly copied?
Can we also have a atomic_check function for connectors, so the
crtc_state->connectors_changed can be set there? It would be cleaner
and more atomic-like.
To match the legacy behavior, format can be changed by probing just like
in legacy mode.
Changes since v1:
- Add intel_encoder->swap_state to allow updating connector state.
- Add intel_tv->format for detect_mode and mode_valid, updated on atomic commit.
Changes since v2:
- Fix typo in tv_choose_preferred modes function name.
- Assignment of tv properties is done in core, so intel_tv only needs
a atomic_check function. Thanks Ville!
Changes since v3:
- connection_mutex is now held in mode_valid() and get_modes(),
this removes the need for caching parts of the connector_state.
Changes since v4:
- Use the new atomic connector check function.
