Previous cover:
This series is a rework of "piix4: cleanup and improvements" [1]
from Hervé, and my "remove i386/pc dependency: PIIX cleanup" [2].
Still trying to remove the strong X86/PC dependency 2 years later,
one step at a time.
Here we split the PIIX3 southbridge from i440FX northbridge.
The i440FX northbridge is only used by the PC machine, while the
PIIX southbridge is also used by the Malta MIPS machine.
This is also a step forward using KConfig with the Malta board.
Without this split, it was impossible to compile the Malta without
pulling various X86 pieces of code.
The overall design cleanup is not yet perfect, but enough to post
as a series.
Now that the PIIX3 code is extracted, the code duplication with the
PIIX4 chipset is obvious. Not worth improving for now because it
isn't broken.

Philippe,
It looks you are very busy these days. Do you mind my integrating this
series in next Mips queue, in its present v2 state? (You can certainly do
further refinements later on.)

As far as I can tell, a handful of checkpatch warnings are all false
positives.
Peter, I am fine with Philippe (or Herve for that matter) submitting this
series as a pull request (providing that some basic relevant Malta tests
are done), and, if you are fine too, I think we can proceed.
Integrating this series will make device model for Malta better (closer to
real hardware), and also help Philippe continue working on other device
cleanups.
