[PATCH 09/27] drm: edid: Constify connector argument to infoframe functions

[Laurent Pinchart <laurent.pinchart+renesas@xxxxxxxxxxxxxxxx>]

The drm_hdmi_avi_infoframe_from_display_mode(),
drm_hdmi_vendor_infoframe_from_display_mode() and
drm_hdmi_avi_infoframe_quant_range() functions take a drm_connector that
they don't modify. Mark it as const.
