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>

    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.

+Timer64
+-------
+
+The timer64 node describes C6X event timers.
+
+Required properties:
+
+- compatible: must be "ti,c64x+timer64"
+- reg: base address and size of register region
+- interrupt-parent: interrupt controller
+- interrupts: interrupt id
+
+Optional properties:
+
+- ti,dscr-dev-enable: Device ID used to enable timer IP through DSCR interface.
+
+- ti,core-mask: on multi-core SoCs, bitmask of cores allowed to use this timer.
+
+Example:
+	timer0: timer@25e0000 {
+		compatible = "ti,c64x+timer64";
+		ti,core-mask = < 0x01 >;
+		reg = <0x25e0000 0x40>;
+		interrupt-parent = <&megamod_pic>;
+		interrupts = < 16 >;
+	};
