Pushed to drm-rust-next with the changes I mentioned inline, thanks!

We will definitely want to make our interfaces evolves some more
(notably the command queue), and there are still a few nits to address,
but we have been kicking the can down the road for quite some time with
this one and in its current shape it provides a good foundation for the
next stuff to build upon.

The GSP is now initialized - not that it does anything beyond telling us
its name, but it's a milestone nonetheless! :)
