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.

+This binding uses the common clock binding:
+Documentation/devicetree/bindings/clock/clock-bindings.txt
+
+Currently various "fixed" clocks are declared for peripheral drivers that use
+the common clock framework to reference their core clocks. Proper support of
+these clocks will be added later
+
+Device tree example:
+
+	clocks {
+		#address-cells = <1>;
+		#size-cells = <1>;
+		ranges;
+
+		osc: oscillator {
+			compatible = "fixed-clock";
+			#clock-cells = <1>;
+			clock-frequency = <25000000>;
+		};
+
+		apb_clk: apb_clk {
+			compatible = "fixed-clock";
+			#clock-cells = <0>;
+			clock-frequency = <1000000000>;
+		};
+
+		periph_clk: periph_clk {
+			compatible = "fixed-clock";
+			#clock-cells = <0>;
+			clock-frequency = <500000000>;
+		};
+	};
