The Freescale PCI-e controllers have an issue in that they use the
PCI_PRIMARY_BUS register in the virtual P2P bridge to determine which
bus number to match on when generating a type 0 config cycle. The
issue is if we are renumbering bus numbers to match Linux we will try
setting the PCI_PRIMARY_BUS and will not know which bus number to use
for generating type 0 config cycles. We surpress writing the register
in the P2P bridge and always keep it at zero.
In the future when proper PCI domain support is working we should be
able to remove this.

There are times that we need to know which controller we are on to decide
how to exclude devices properly. We now pass the pci_controller that we
are going to use down to the pci_exclude_device function. This will
greatly simplify being able to exclude the PHBs in multiple controller
setups.

The Freescale and Marvell PCI controllers dont require explicit setting for
type 1 config cycles. They handle producing them by implicitly looking at the
bus, devfn.
The TSI108 and 52xx don't use the generic PCI indirect code and thus don't
bother with set_cfg_type.

When CONFIG_PCI is disabled, the definitions for isa_io_base,
isa_mem_base and pci_dram_offset are entirely unused, but they
can result in link failure because they are defined in multiple
places.
The easiest fix is to just remove all these definitions.

Many platforms currently define their own add_bridge function, some
of them globally. This breaks some multiplatform configurations.
Prefixing each of these functions with the platform name avoids
this problem.

The cores used in the MPC82xx/83xx/86xx embedded controllers are very similar
to those in the 32 bit general-purpose processors, so it makes sense to
treat them as the same CPU family.
Choosing between the embedded platforms and the multiplatform code is
now done in the platform menu, but functionally everything stays the
same.

Commit d1953c8888 removed the use of
4level-fixup.h for 32-bit systems under arch/powerpc. However, I
missed a few things activated on some configurations, resulting in
some warnings (at least with STRICT_MM_TYPECHECKS enabled) and build
errors in some circumstances. This fixes it.

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.
