[PATCH 1/2] staging/vc04_services: Register a platform device for the camera driver.

[Eric Anholt]

We had the camera driver set up in a module_init function, but that
meant that the camera driver would fail to load if it was initialized
before VCHI.  This enforces that it loads after we've successfully set
up.

I'm going to try to get Dave Stevenson's new v4l2 codec driver merged
to staging (my primary motivation for getting vchi merged in the first
place!), and since his series touches the camera driver I needed to
probe the camera successfully in order to test it.
