Add the rt linux 4.1.3-rt3 as base

Import the rt linux 4.1.3-rt3 as OPNFV kvm base.

It's from git://git.kernel.org/pub/scm/linux/kernel/git/rt/linux-rt-devel.git linux-4.1.y-rt and
the base is:

commit 0917f823c59692d751951bf5ea699a2d1e2f26a2
Author: Sebastian Andrzej Siewior <bigeasy@linutronix.de>
Date:   Sat Jul 25 12:13:34 2015 +0200

    Prepare v4.1.3-rt3

We lose all the git history this way and it's not good. We
should apply another opnfv project repo in future.

+* Renesas RCar PCIe interface
+
+Required properties:
+- compatible: should contain one of the following
+	"renesas,pcie-r8a7779", "renesas,pcie-r8a7790", "renesas,pcie-r8a7791"
+- reg: base address and length of the pcie controller registers.
+- #address-cells: set to <3>
+- #size-cells: set to <2>
+- bus-range: PCI bus numbers covered
+- device_type: set to "pci"
+- ranges: ranges for the PCI memory and I/O regions.
+- dma-ranges: ranges for the inbound memory regions.
+- interrupts: two interrupt sources for MSI interrupts, followed by interrupt
+	source for hardware related interrupts (e.g. link speed change).
+- #interrupt-cells: set to <1>
+- interrupt-map-mask and interrupt-map: standard PCI properties
+	to define the mapping of the PCIe interface to interrupt
+	numbers.
+- clocks: from common clock binding: clock specifiers for the PCIe controller
+	and PCIe bus clocks.
+- clock-names: from common clock binding: should be "pcie" and "pcie_bus".
+
