drm: Extract drm_drv.h
I want to move dumb buffer documentation into the right vfuncs, and for that I first need to be able to pull that into kerneldoc without having to clean up all of drmP.h. Also, header-splitting is nice. While at it shuffle all the function declarations for drm_drv.c into the right spots, and drop the kerneldoc for drm_minor_acquire/release since it's only used internally. v2: Keep all existing copyright notices (Chris).
