[PATCH v4 02/13] drm/bridge: analogix_dp: Move &drm_bridge_funcs.mode_set to &drm_bridge_funcs.atomic_enable

[Damon Ding <damon.ding@rock-chips.com>]

According to the include/drm/drm_bridge.h, the callback
&drm_bridge_funcs.mode_set is deprecated and it should be better to
include the mode setting in the &drm_bridge_funcs.atomic_enable instead.
