ioctl instead of -ENOMEM.

c671e1e302 drm/vc4: fix warning in validate printf.
This just fixes a warning on 64-bit builds:

  drivers/gpu/drm/vc4/vc4_validate.c: In function ‘validate_gl_shader_rec’:
  drivers/gpu/drm/vc4/vc4_validate.c:864:12: warning: format ‘%d’ expects argument of type ‘int’, but argument 4 has type ‘size_t {aka long unsigned int}’ [-Wformat=]

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.
