This patch adds support for AppliedMicro X-Gene PCIe host controller. The
driver is tested on X-Gene platform with different gen1/2/3 PCIe endpoint
cards.

X-Gene PCIe controller driver has depedency on the pcie arm64 arch support.
Liviu Dudau from ARM has sent a patch set for pcie arm64 arch support and
support for creating generic pcie bridge from device tree. Liviu's patches
are available here
https://lkml.org/lkml/2014/9/23/852

If someone wishes to test PCIe on X-Gene with this patch set, above mentioned
patches from Liviu must be applied before the patches in this patch set. Also
please use latest xgene u-boot firmware.

I applied these on pci/host-xgene (based on pci/host-generic).  I hope to
merge these for v3.18.  It'd be nice to have a device tree person like Arnd
or Rob take a look at the arch/arm64/boot/dts/ bits.

Those changes should normally go through the arm-soc tree, but we
have not done that so far for arm64 stuff, so I'm not blaming anybody.

The dts changes all look good to me, and I think it's ok to have them
go through your tree this time.

In the future, we should all have an eye on this more to ensure that
the .dts changes all go through arm-soc.

The arch/arm64/boot/dts patch is at the tip of my branch, and I'd be
more than happy to drop it.  It would be nice to have it in v3.18
along with the driver, though, so I'll keep it until somebody chimes
in to put it in arm-soc.

Thanks Bjorn and Arnd.
