[PATCH] drm: add documentation for tv connector state margins

[Jani Nikula]

A bit boring documentation fix, but gets rid of the warnings:

./include/drm/drm_connector.h:370: warning: Function parameter or member 'margins.left' not described in 'drm_tv_connector_state'
./include/drm/drm_connector.h:370: warning: Function parameter or member 'margins.right' not described in 'drm_tv_connector_state'
./include/drm/drm_connector.h:370: warning: Function parameter or member 'margins.top' not described in 'drm_tv_connector_state'
./include/drm/drm_connector.h:370: warning: Function parameter or member 'margins.bottom' not described in 'drm_tv_connector_state'
