v3:
* Fix in comment: AC97 Modem -> MC97 Modem (Zoltan)
* Introduce TYPE_VT82C686B_USB_UHCI define (Zoltan)
* Introduce TYPE_VIA_IDE define (for consistency)

v3:
* Replace pre increment by post increment in for loop (Zoltan)
* Move class defines close to where the class is defined (Zoltan)

Testing done:
* `make check-avocado`
  Passes for boot_linux_console.py for mips64el_fuloong2e
* `qemu-system-ppc -machine pegasos2 -rtc base=localtime -device ati-vga,guest_hwcursor=true,romfile="" -cdrom morphos-3.17.iso -kernel morphos-3.17/boot.img`
  Boots successfully and it is possible to open games and tools.

v2:
* Keep the call to pci_ide_create_devs() in board code for consistency (Zoltan)
* Create rtc-time alias in board rather than in south bridge code
* Remove stale comments about PCI functions (Zoltan)

v1:
This series instantiates all PCI functions of the VT82xx south bridges in the south bridges themselves.
For the IDE function this is especially important since its interrupt routing is configured in the
ISA function, hence doesn't make sense to instantiate it as a "Frankenstein" device. The interrupt
routing is currently hardcoded and changing that is currently not in the scope of this series.

Testing done:
* `qemu-system-ppc -machine pegasos2 -rtc base=localtime -device ati-vga,guest_hwcursor=true,romfile="" -cdrom morphos-3.17.iso -kernel morphos-3.17/boot.img`
  Boots successfully and it is possible to open games and tools.

* I was unable to test the fuloong2e board even before this series since it seems to be unfinished [1].
  A buildroot-baked kernel [2] booted but doesn't find its root partition, though the issues could be in the buildroot receipt I created.
