Make these fields in PIIX4PMState to avoid the allocation.

Use pci_address_space_io() instead.

Please pass either pci_address_space_io() or isa_io_address_space()
(you'll have to write the latter) to cirrus_init_common() from its
callers. We really want to avoid get_system_io().

Using offsets from 0x400 is... wierd. It's not like there's a vga where
the ports are all bunched together.

This doesn't need to be a portio list, it can be a simple MemoryRegionOps.

Should we just remove serial_init() and replace it with the serial-isa
QOM class?
If not, just pass the io address space from the caller.
