Makes more sense and gives better grouping in the DocBook function reference sections. To make this possible we need to expose two functions from drm_crtc.c though. To avoid further namespace pollution in the system wide headers create a new internal header for such drm internal symbols. I expect that longer-term we'll add tons more, but since my goal here is to polish the kerneldoc that's for another day.
