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.

+* Xillybus driver for generic FPGA interface
+
+Required properties:
+- compatible: Should be "xillybus,xillybus-1.00.a"
+- reg: Address and length of the register set for the device
+- interrupts: Contains one interrupt node, typically consisting of three cells.
+- interrupt-parent: the phandle for the interrupt controller that
+                    services interrupts for this device.
+
+Optional properties:
+- dma-coherent: Present if DMA operations are coherent
+
+Example:
+
+	xillybus@ff200400 {
+		compatible = "xillybus,xillybus-1.00.a";
+		reg = < 0xff200400 0x00000080 >;
+		interrupts = < 0 40 1 >;
+		interrupt-parent = <&intc>;
+	} ;
