Similar motivation to other similar recent attempt[1].  But with an
attempt to have some shared code for this.  As well as documentation.

It is probably a bit UMA-centric, I guess devices with VRAM might want
some placement stats as well.  But this seems like a reasonable start.

Basic gputop support: https://patchwork.freedesktop.org/series/116236/
And already nvtop support: https://github.com/Syllo/nvtop/pull/204

I've combined the separate series to add comm/cmdline override onto
the end of this, simply out of convenience (they would otherwise
conflict in a bunch of places).

v2: Extend things to allow for multiple regions other than just system
    "memory", make drm_show_memory_stats() a helper so that, drivers
    can use it or not based on their needs (but in either case, re-
    use drm_print_memory_stats()
v3: Docs fixes
v4: use u64 for drm_memory_stats, small docs update and collected
    Tvrtko's a-b
v5: Rebase on drm-misc-next, drop comm/cmdline override patches
