Subject: [PATCH] drm/panel: himax-hx8394: Populate connector bus formats

Add a call to drm_display_info_set_bus_formats() in hx8394_get_modes()
to populate the connector's bus_formats field with the panel's bus
format.This ensures display bus format information is available to other
components that may need it later such as to identify and match the input
bus format correctly based on the panel description.
