[PATCH 1/3] drivers/gpu/drm: fix sparse warnings: make symbols static

[Hannes Eder <hannes@hanneseder.net>]

Fix this sparse warnings:

  drivers/gpu/drm/drm_crtc.c:270:17: warning: symbol 'drm_crtc_from_fb' was not declared. Should it be static?
  drivers/gpu/drm/drm_crtc.c:810:5: warning: symbol 'drm_mode_group_init' was not declared. Should it be static?
  drivers/gpu/drm/drm_crtc.c:913:6: warning: symbol 'drm_crtc_convert_to_umode' was not declared. Should it be static?
  drivers/gpu/drm/drm_crtc.c:945:6: warning: symbol 'drm_crtc_convert_umode' was not declared. Should it be static?
  drivers/gpu/drm/drm_edid.c:252:25: warning: symbol 'drm_mode_std' was not declared. Should it be static?
  drivers/gpu/drm/drm_modes.c:446:6: warning: symbol 'list_sort' was not declared. Should it be static?
