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}. Signed-off-by: Bernhard Beschow <shentey@gmail.com> Message-Id: <20240114123911.4877-10-shentey@gmail.com> Reviewed-by: Michael S.
