Subject: [PATCH v3 1/2] arm64: dts: Add 1 more window with large size for X-Gene PCIe nodes

This patch adds 1 additional window with large size (up to 64GB) for
X-Gene PCIe nodes to support devices that require huge BAR.

Each X-Gene PCIe node now will have 2 memory windows:1 non-prefetchable
32-bit window and 1 prefetchable 64-bit window.
