Well, mostly drm_file.h, and clean up all related things:
- I didnt' figure out the difference between preclose and postclose.
The existing explanation in drm-internals.rst didn't convince me,
since it's also really outdated - we clean up pending DRM events in
the core nowadays. I put a FIXME in for the future.
- Another FIXME is to have a macro for default fops.
- Lots of links all around, main areas are to tie the overview in
drm_file.c more into the callbacks in struct drm_device, and the
other is to link render/primary node code to the right sections in
drm-uapi.rst.
- Also moved the open/close stuff to drm_drv.h from drm-internals.rst,
seems like the better place for that information. Since that section
was rather outdated this amounted to full-on rewrite.
A big missing piece here is some overview graph, but I think better to
wait with that one until drm_device and drm_driver are also fully
documented.

I'm torn on whether drm_minor really should be here or somewhere else.
Maybe with more clarity after untangling drmP.h more this is easier to
decide, for now I've put a FIXME comment right next to it. Right now
we need struct drm_minor for the inline drm_file type helpers, and so
it does kinda make sense to have them here.
Next patch will kerneldoc-ify the entire pile.

It's not just file ops, but drm_file stuff in general. This is prep
work to extracting a drm_file.h header in the next patch.
