[Why] The current state on the connector is queried when getting the max bpc rather than the new state. This means that a new max bpc value can only currently take effect on the commit *after* it changes. The new state should be passed in instead. [How] Pass down the dm_state as drm state to where we do color depth lookup. The passed in state can still be NULL when called from amdgpu_dm_connector_mode_valid, so make sure that we have reasonable defaults in place. That should probably be addressed at some point. This change now (correctly) causes a modeset to occur when changing the max bpc for a connector.
