Eric Anholt 8483d152db drm/vc4: Remove broken attempt at GPU reset using genpd. 
I've tested and confirmed that it doesn't actually work.  We'll need
to sort out how to do this properly later, but for now just remove it
since it also caused build breakage due to using CONFIG_PM_SLEEP
functions without our Kconfig depending on PM_SLEEP.

Eric Anholt 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.

Eric Anholt d3f5168a08 drm/vc4: Bind and initialize the V3D engine. 
This is the component of the GPU that does 3D rendering.
