Make it so we do a runtime check to know if we need to write cfg_addr
as big or little endian.  This is needed if we want to allow 86xx support
to co-exist in the same kernel as other 6xx PPCs.

The newer Arcadia boards for CDS have an FPGA that shows up on PCI
however isn't a real PCI device.  Add a quirk to just ignore the
FPGA.

This is based on the following patch from Andy & York:

On the 85xx/86xx PCIe controllers if there is no device connected to the
PHB we will still allocate a pci_bus for downstream bus of the virtual
P2P bridge. However the resources allocated to the downstream bus are not
correct and so we just mimic the resources from the upstream pci_bus.

Use the PCI capabilities to determine if we are PCIe PHB.  Also use
PPC_INDIRECT_TYPE_NO_PCIE_LINK since the Freescale PCIe controllers
will lock the system if they don't have link and you try to do a config
access to anything but the PHB.

Added PPC_INDIRECT_TYPE_NO_PCIE_LINK flag to the indirect pci handling
code to ensure that we don't talk to any device other than the PHB

The recent 9p commit: bd238fb4 that
supposedly only moved files also introduced a new 9p sysctl interface
that did not properly register it's sysctl binary numbers.

And since it was only for debugging clearly did not need a binary fast
path in any case.  So this patch just remove the binary numbers.

See Documentation/sysctl/ctl_unnumbered.txt for more details.

While I was at it I cleaned up the sysctl initializers a little as
well so there is less to read.
