drm/amd/display: update connector->display_info after read edid
[Why] drm_connector->display_info is not passed to amdgpu_dm right way after read edid. [How] display_info is parsed from edid and saved into drm_connector by drm_connector_update_edid_proerty which is called within amdgpu_dm_update_connector_after_detect. call this function after read edid to update drm_connector->display_info Signed-off-by: Hersen Wu <hersenxs.wu@amd.com> Reviewed-by: Bhawanpreet Lakha <Bhawanpreet.Lakha@amd.com> Acked-by: Rodrigo Siqueira <Rodrigo.Siqueira@amd.com> Signed-off-by: Alex Deucher <alexander.deucher@amd.com>
