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:

    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.

+TI SoC Davinci/Keystone2 MDIO Controller Device Tree Bindings
+---------------------------------------------------
+
+Required properties:
+- compatible		: Should be "ti,davinci_mdio" or "ti,keystone_mdio"
+- reg			: physical base address and size of the davinci mdio
+			  registers map
+- bus_freq		: Mdio Bus frequency
+
+Optional properties:
+- ti,hwmods		: Must be "davinci_mdio"
+
+Note: "ti,hwmods" field is used to fetch the base address and irq
+resources from TI, omap hwmod data base during device registration.
+Future plan is to migrate hwmod data base contents into device tree
+blob so that, all the required data will be used from device tree dts
+file.
+
+Examples:
+
+	mdio: davinci_mdio@4A101000 {
+		compatible = "ti,davinci_mdio";
+		reg = <0x4A101000 0x1000>;
+		bus_freq = <1000000>;
+	};
+
+(or)
+
+	mdio: davinci_mdio@4A101000 {
+		compatible = "ti,davinci_mdio";
+		ti,hwmods = "davinci_mdio";
+		bus_freq = <1000000>;
+	};
