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.

+LSI Axxia I2C
+
+Required properties :
+- compatible : Must be "lsi,api2c"
+- reg : Offset and length of the register set for the device
+- interrupts : the interrupt specifier
+- #address-cells : Must be <1>;
+- #size-cells : Must be <0>;
+- clock-names : Must contain "i2c".
+- clocks: Must contain an entry for each name in clock-names. See the common
+  clock bindings.
+
+Optional properties :
+- clock-frequency : Desired I2C bus clock frequency in Hz. If not specified,
+  the default 100 kHz frequency will be used. As only Normal and Fast modes
+  are supported, possible values are 100000 and 400000.
+
+Example :
+
+i2c@02010084000 {
+	compatible = "lsi,api2c";
+	device_type = "i2c";
+	#address-cells = <1>;
+	#size-cells = <0>;
+	reg = <0x20 0x10084000 0x00 0x1000>;
+	interrupts = <0 19 4>;
+	clocks = <&clk_per>;
+	clock-names = "i2c";
+	clock-frequency = <400000>;
+};
