2c68f1fcfb drm/vc4: Return an ERR_PTR from BO creation instead of NULL. 
Fixes igt vc4_create_bo/create-bo-0 by returning -EINVAL from the
ioctl instead of -ENOMEM.

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.
