drm/doc: Reorg for drm-kms.rst
- Again adjust headings a bit, and don't mix up the initialization sections with other stuff. - Remove the doc for output polling, that vfunc is now properly documented in the vfunc reference sections. - Move the grab-bag with all the core stuff (i.e. drm_crtc.[hc]) to the front for a more prominent place.
