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.

+* Central Interrupt Unit
+
+Properties:
+- compatible: "cavium,octeon-3860-ciu"
+
+  Compatibility with all cn3XXX, cn5XXX and cn63XX SOCs.
+
+- interrupt-controller:  This is an interrupt controller.
+
+- reg: The base address of the CIU's register bank.
+
+- #interrupt-cells: Must be <2>.  The first cell is the bank within
+   the CIU and may have a value of 0 or 1.  The second cell is the bit
+   within the bank and may have a value between 0 and 63.
+
+Example:
+	interrupt-controller@1070000000000 {
+		compatible = "cavium,octeon-3860-ciu";
+		interrupt-controller;
+		/* Interrupts are specified by two parts:
+		 * 1) Controller register (0 or 1)
+		 * 2) Bit within the register (0..63)
+		 */
+		#interrupt-cells = <2>;
+		reg = <0x10700 0x00000000 0x0 0x7000>;
