Subject: [PATCH v4 11/17] drm/bridge: analogix_dp: Add a new member aux to struct analogix_dp_plat_data

The member struct drm_dp_aux aux of struct analogix_dp_plat_data can
help to get panel information through the DP AUX bus, which is the
more recommended way to obtain eDP panel compared with platform bus.
