We can use a i440FX without the IGD passthrough host bridge.
Extract it into a new file, 'hw/pci-host/xen_igd_pt.c'.

Use definitions from "hw/pci/pci_regs.h".
This also helps when using git-grep.

We don't enforce the -Wsign-conversion CPPFLAG, but it doesn't hurt
to avoid this warning:
warning: implicit conversion changes signedness: 'int' to 'size_t' (aka 'unsigned long') [-Wsign-conversion]

Make the PCII440FXState structure public, so it can be used out of
this source file. This will allow us to extract the IGD Passthrough
Host Bridge, which is a children of the TYPE_I440FX_PCI_DEVICE.

Missed during the refactor in commits 14a026dd58 and 0f25d865a,
this file is now only about the i440FX chipset.

The PIIX3 is not tied to the i440FX and can even be used without it.
Move its creation to the machine code (pc_piix.c).
We have now removed the last trace of southbridge code in the i440FX
northbridge.

We moved all the PIIX3 southbridge code out of hw/pci-host/piix.c,
it now only contains i440FX northbridge code.
Rename it to match the chipset modelled.
