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

    Signed-off-by: Sebastian Andrzej Siewior <bigeasy@linutronix.de>

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

+OMAP SoC HWRNG Module
+
+Required properties:
+
+- compatible : Should contain entries for this and backward compatible
+  RNG versions:
+  - "ti,omap2-rng" for OMAP2.
+  - "ti,omap4-rng" for OMAP4, OMAP5 and AM33XX.
+  Note that these two versions are incompatible.
+- ti,hwmods: Name of the hwmod associated with the RNG module
+- reg : Offset and length of the register set for the module
+- interrupts : the interrupt number for the RNG module.
+		Only used for "ti,omap4-rng".
+
+Example:
+/* AM335x */
+rng: rng@48310000 {
