target-ppc: Use interrupts for escc
When using the escc with Linux, we need interrupts. So instead of creating a dummy device, let's just map them to the openpic we have anyways. This makes Linux on PPC64 with console=ttyPZ0 work. Obviously, this change needs to be reflected in openbios. Patch for that follows this one. Please update the binary then.
