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.

+* Cadence MACB/GEM Ethernet controller
+
+Required properties:
+- compatible: Should be "cdns,[<chip>-]{macb|gem}"
+  Use "cdns,at91sam9260-macb" for Atmel at91sam9 SoCs or the 10/100Mbit IP
+  available on sama5d3 SoCs.
+  Use "cdns,at32ap7000-macb" for other 10/100 usage or use the generic form: "cdns,macb".
+  Use "cdns,pc302-gem" for Picochip picoXcell pc302 and later devices based on
+  the Cadence GEM, or the generic form: "cdns,gem".
+  Use "cdns,sama5d3-gem" for the Gigabit IP available on Atmel sama5d3 SoCs.
+  Use "cdns,sama5d4-gem" for the Gigabit IP available on Atmel sama5d4 SoCs.
+- reg: Address and length of the register set for the device
+- interrupts: Should contain macb interrupt
+- phy-mode: See ethernet.txt file in the same directory.
+- clock-names: Tuple listing input clock names.
+	Required elements: 'pclk', 'hclk'
+	Optional elements: 'tx_clk'
+- clocks: Phandles to input clocks.
+
+Examples:
+
+	macb0: ethernet@fffc4000 {
+		compatible = "cdns,at32ap7000-macb";
+		reg = <0xfffc4000 0x4000>;
+		interrupts = <21>;
+		phy-mode = "rmii";
+		local-mac-address = [3a 0e 03 04 05 06];
+		clock-names = "pclk", "hclk", "tx_clk";
+		clocks = <&clkc 30>, <&clkc 30>, <&clkc 13>;
+	};
