The idea is to move more and more things into the pbm,
with the eventual goal of eliminating the pci_controller_info
entirely as there really isn't any need for it.

This stage of the transformations requires some reworking of
the PCI error interrupt handling.

It might be tricky to get rid of the pci_controller_info parenting for
a few reasons:

1) When we get an uncorrectable or correctable error we want
   to interrogate the IOMMU and streaming cache of both
   PBMs for error status.  These errors come from the UPA
   front-end which is shared between the two PBM PCI bus
   segments.

   Historically speaking this is why I choose the datastructure
   hierarchy of pci_controller_info-->pci_pbm_info

2) The probing does a portid/devhandle match to look for the
   'other' pbm, but this is entirely an artifact and can be
   eliminated trivially.

What we could do to solve #1 is to have a "buddy" pointer from one pbm
to another.

Namely bus-range and ino-bitmap.

This allows us also to eliminate pci_controller_info's
pci_{first,last}_busno fields as only the pbm ones are
used now.

We fake up a dummy one in all cases because that is the simplest
thing to do and it happens to be necessary for hypervisor systems.

It can be done for every PCI configuration using OF properties.

The only user was bus_dvma_to_mem() which is no longer used
by any driver, so kill that, and the export of pci_memspace_mask.

The only user now is the PCI mmap support code.

Almost entirely taken from the 64-bit PowerPC PCI code.

This allowed to eliminate a ton of cruft from the sparc64
PCI layer.

One thing this change pointed out was that we really should
pull the "get 'local-mac-address' property" logic into a helper
function all the network drivers can call.

Initial git repository build. I'm not bothering with the full history,
even though we have it. We can create a separate "historical" git
archive of that later if we want to, and in the meantime it's about
3.2GB when imported into git - space that would just make the early
git days unnecessarily complicated, when we don't have a lot of good
infrastructure for it.

Let it rip!
