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 FSI
+
+Required properties:
+- compatible			: "renesas,fsi2-<soctype>",
+				  "renesas,sh_fsi2" or "renesas,sh_fsi" as
+				  fallback.
+				  Examples with soctypes are:
+				    - "renesas,fsi2-r8a7740" (R-Mobile A1)
+				    - "renesas,fsi2-sh73a0" (SH-Mobile AG5)
+- reg				: Should contain the register physical address and length
+- interrupts			: Should contain FSI interrupt
+
+- fsia,spdif-connection		: FSI is connected by S/PDIF
+- fsia,stream-mode-support	: FSI supports 16bit stream mode.
+- fsia,use-internal-clock	: FSI uses internal clock when master mode.
+
+- fsib,spdif-connection		: same as fsia
+- fsib,stream-mode-support	: same as fsia
+- fsib,use-internal-clock	: same as fsia
+
+Example:
+
+sh_fsi2: sh_fsi2@0xec230000 {
+	compatible = "renesas,sh_fsi2";
+	reg = <0xec230000 0x400>;
+	interrupts = <0 146 0x4>;
+
+	fsia,spdif-connection;
+	fsia,stream-mode-support;
+	fsia,use-internal-clock;
