I've tested it with CONFIG_PARPORT_PC_SUPERIO both set and unset,
but on parallel port without one of such SIOs needing special setup.

However, considering that this patch only moves PCI SIO access code
behind this config option (just like ISA one is currently) and doesn't
alter the actual setup functionality I don't expect problems here.
