In order to reset the GPU early on in the module load sequence, we need to allocate the basic engine structs (to populate the mmio offsets etc). Currently, the engine initialisation allocates both the base struct and also allocate auxiliary objects, which depend upon state setup quite late in the load sequence. We split off the allocation callback for later and allow ourselves to allocate the engine structs themselves early. v2: Different paint for the unwind following error.
