[0/2] drm/panic: Allows to run with fbcon

fbcon and drm_panic cannot be built together because they both write
to the screen when a panic occurs, leading to a corrupted panic image.
With this 2 patches, drm_panic will disable the fbdev output before
writing the panic screen, so only drm_panic screen will be shown.

  drm/fb-helper: Add drm_fb_helper_emergency_disable
  drm/panic: Allows to run with fbcon
