Add a new Kconfig for the accel subsystem. The Kconfig currently
contains only the basic CONFIG_ACCEL option that will be used to
decide whether to compile the accel registration code as part of the
drm core functionality.
I have taken the liberty to appropriate the dri-devel mailing list and
the dri-devel IRC channel for the accel subsystem.

YOu never use drivers/accel/ again in this patch series, was that
intentional?

Yes, because I didn't plan for accel to have any core code at this stage.
But according to your other comments, this will probably change
(unless someone thinks otherwise).

I'm willing to assist with reviews, etc. While I appreciate your
efforts to drive this, you shouldn't be taking on everything going
forward. Feel free to add me (or don't) to this entry as you see fit.
