[PATCH 06/20] drm: move AGP definitions harder

[David Herrmann <dh.herrmann@xxxxxxxxx>]

Move drm_agp_head to drm_agpsupport.h and drm_agp_mem into drm_legacy.h.
Unfortunately, drivers still heavily access drm_agp_head so we cannot
move it to drm_legacy.h. However, at least it's no longer visible in
drmP.h now (it's directly included from it, though).
