graphics/mesa-devel: work around userptr for anv on gen < 8 and iris compute

Vulkan on Intel Broadwell or later uses softpin but older need userptr:

   /* We only allow 48-bit addresses with softpin because knowing the actual
    * address is required for the vertex cache flush workaround.
    */
   device->supports_48bit_addresses = (device->info.gen >= 8) &&
                                      device->has_softpin &&
                                      device->gtt_size > (4ULL << 30 /* GiB */);

   device->use_softpin = device->has_softpin &&
                         device->supports_48bit_addresses;
