[POWERPC] 85xx: Add quirk to ignore bogus FPGA on CDS
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: http://ozlabs.org/pipermail/linuxppc-dev/2007-February/032042.html Signed-off-by: Kumar Gala <galak@kernel.crashing.org>
