Various changes for in-kernel modesetting:

  - allow drm_buffer_object_create to be called w/o dev_mapping
  - fixup i915 init code to allocate memory, fb and set modes right
  - pass fb to drm_initial_config for setup
  - change some debug output to make it easier to spot
  - fixup lvds code to use DDC probing correctly
