Apparently in hardware (as opposed to simulation), the clear colors
need to be uploaded before the render config, otherwise they won't
take effect. Fixes igt's vc4_wait_bo/used-bo-* subtests.

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.
