drm/rockchip: Fix return type of cdn_dp_connector_mode_valid
The mode_valid field in drm_connector_helper_funcs is expected to be of
type:
enum drm_mode_status (* mode_valid) (struct drm_connector *connector,
struct drm_display_mode *mode);
The mismatched return type breaks forward edge kCFI since the underlying
function definition does not match the function hook definition.
The return type of cdn_dp_connector_mode_valid should be changed from
int to enum drm_mode_status.
