The PCI core supports an offset per aperture nowadays but our arch
code still has a single offset per host bridge representing the
difference betwen CPU memory addresses and PCI MMIO addresses.

This is a problem as new machines and hypervisor versions are
coming out where the 64-bit windows will have a different offset
(basically mapped 1:1) from the 32-bit windows.

This fixes it by using separate offsets. In the long run, we probably
want to get rid of that intermediary struct pci_controller and have
those directly stored into the pci_host_bridge as they are parsed
but this will be a more invasive change.

To build arch/powerpc without including asm-ppc/ we need these files
in asm-powerpc/

Moved some headers under arch/powerpc/platforms if they were only used by
platform or driver files and fixed up the source file includes to match
the new locations

This patch removes all self references and fixes references to files
in the now defunct arch/ppc64 tree.  I think this accomplises
everything wanted, though there might be a few references I missed.

Implemented by  modification of the .name field of the platform device,
when PDs with the
same names are to be used within different drivers, as
<device_name> -> <device_name>:<function>
Corresponding drivers should change the .name in struct device_driver to
reflect upper of course.

Added ppc_sys_device_disable/enable function set, making it easier to
disable all the inexistent/not utilized platform device way pdevs. By the
check of the "disabled" bit in the config field of ppc_sys_specs, disabled
platform devices will be either added/removed from the bus, or simply not
registered on it, depending on the time when disable/enable call asserted.

The default behaviour when nothing is disabled/enabled will be "all devices
are enabled", which is the same as before.

Also helper platform_notify_map function added, making assignment of
board-specific platform_info more consistent and generic.

The UARTs on the MPC824x are unique devices and really shouldn't be thought
of as a DUART.  In addition, if both UARTs are in use we need to configure
the part to enable the 2nd UART since the pins for the UARTs are
multiplexed.  Adds support to run the 824x Sandpoint with both UARTs if
desired.

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!
