[PATCH 2/3] drivers/gpu/drm: fix sparse warnings: unexport symbols

[Hannes Eder <hannes@hanneseder.net>]

Fix this sparse warnings:

  drivers/gpu/drm/drm_crtc_helper.c:137:6: warning: symbol 'drm_helper_probe_connector_modes' was not declared. Should it be static?
  drivers/gpu/drm/drm_modes.c:360:6: warning: symbol 'drm_mode_validate_clocks' was not declared. Should it be static?
