This patch reworks the way IRQs are fixed up on PCI for arch powerpc.
It makes pci_read_irq_line() called by default in the PCI code for
devices that are probed, and add an optional per-device fixup in
ppc_md for platforms that really need to correct what they obtain
from pci_read_irq_line().
It also removes ppc_md.irq_bus_setup which was only used by pSeries
and should not be needed anymore.
I've also removed the pSeries s7a workaround as it can't work with
the current interrupt code anyway. I'm trying to get one of these
machines working so I can test a proper fix for that problem.
I also haven't updated the old-style fixup code from 85xx_cds.c
because it's actually buggy :) It assigns pci_dev->irq hard coded
numbers which is no good with the new IRQ mapping code. It should
at least use irq_create_mapping(NULL, hard_coded_number); and possibly
also set_irq_type() to set them as level low.

mpc832x, as in mpc8360, needs to explicitly find and create the
platform device for ucc_geth in 2.6.19. This code will likely be
readapted to Benh's new of_ methods for 2.6.20.

Add support for MPC832x MDS evaluation board.
This patch depends on the 8360+QE lib patches by Leo.
The MPC832x processors (MPC8323E, MPC8323, MPC8321E, MPC8321) sport
the e300c2 core plus a QUICC Engine (QE). This patch adds support for
the 832x MDS evaluation board.
The 832x MDS dts and defconfig files are pending more tests.

Now that get_property() returns a void *, there's no need to cast its

Removed platform_init usage on 83xx and 85xx and use define_machine and
probe(). For now we always return true in the problem since you can only
build for one specific board at a time. This is an artificial constraint.
When we get ride of it we will need to update the Kconfig's for these
sub-arch's and make the board's probe() functions actually do something.
