I actually tried to write that platform hooks, but unfortunately I'm
quite far from being able to test them.

The stuff I'm submitting is not ready for proper review. It will take
a while before it is good enough. But I believe it has place in
staging: it will allow me to get Dream into usable state, and will
allow others to help with cleanups.

Of course, it will get proper review before moving to drivers/input.
