hw/char/parallel-isa: Implement relocation and enabling/disabling for TYPE_ISA_PARALLEL
The real SuperI/O chips emulated by QEMU allow for relocating and enabling or
disabling their SuperI/O functions via software. So far this is not implemented.
Prepare for that by adding isa_parallel_set_{enabled,iobase}.
