[PATCH v6 16/22] drm: bridge: dw_hdmi: Use display_info is_hdmi and has_audio

[Jonas Karlman <jonas@kwiboo.se>]

drm_edid_connector_update() is being called from bridge connector funcs
and from detect and force funcs for dw-hdmi connector.

Change to use is_hdmi and has_audio from display_info directly instead
of keeping our own state in sink_is_hdmi and sink_has_audio.

Also remove the old and unused edid struct member and related define.
