intel: Set a more useful fake devinfo->gtt_size in no-hw mode

With the old value, anv didn't think that the hardware supported 48-bit
addresses, and hit this assert:

   assert(device->supports_48bit_addresses == !device->use_relocations);

The new value of 1ull << 48 is the one reported on my Icelake machine.
