There is no need for each GPU to have it's own cmdbuf suballocation region. Only allocate a single one for the the etnaviv virtual device and share it across all GPUs. As the suballoc space is now potentially shared by more hardware jobs running in parallel, double its size to 512KB to avoid contention.
