214613656b drm/vc4: Add an interface for capturing the GPU state after a hang. 
This can be parsed with vc4-gpu-tools tools for trying to figure out
what was going on.

v2: Use __u32-style types.

b501bacc60 drm/vc4: Add support for async pageflips. 
An async pageflip stores the modeset to be done and executes it once
the BOs are ready to be displayed.  This gets us about 3x performance
in full screen rendering with pageflipping.

d5b1a78a77 drm/vc4: Add support for drawing 3D frames. 
The user submission is basically a pointer to a command list and a
pointer to uniforms.  We copy those in to the kernel, validate and
relocate them, and store the result in a GPU BO which we queue for
execution.

v2: Drop support for NV shader recs (not necessary for GL), simplify
    vc4_use_bo(), improve bin flush/semaphore checks, use __u32 style
    types.
