[PATCH 20/24] drm/msm/dp: use drm_display_info in mode_valid callbacks

[Dmitry Baryshkov]

The .mode_valid bridge callback is passed the sink's drm_display_info
directly, so msm_dp_bridge_mode_valid() and msm_edp_bridge_mode_valid()
have no need to reach into the stored connector for it. Use the supplied
info pointer and drop the now-pointless !dp->connector guard.
