This patch set adds 1 large (up to 64GB) memory window for each PCIe
controller nodes in X-Gene device tree and fix PCIe controller driver
to handle multiple memory ranges correctly. These changes are required
to support PCIe devices that has huge BAR.

v2 changes:
1. Separate device-tree changes and driver changes into different
patches
2. Explicitly define new large window as 64-bit prefetchable in dts
3. Use IORESOURCE_PREFETCH flag to determine which PCIe controller
register to be used to configure the memory ranges.
