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.

+* Device tree bindings for Allwinner A10, A20 PS2 host controller
+
+A20 PS2 is dual role controller (PS2 host and PS2 device). These bindings are
+for PS2 A10/A20 host controller. IBM compliant IBM PS2 and AT-compatible keyboard
+and mouse can be connected.
+
+Required properties:
+
+ - reg             : Offset and length of the register set for the device.
+ - compatible      : Should be as of the following:
+                     - "allwinner,sun4i-a10-ps2"
+ - interrupts      : The interrupt line connected to the PS2.
+ - clocks          : The gate clk connected to the PS2.
+
+
+Example:
+	ps20: ps2@0x01c2a000 {
+		compatible = "allwinner,sun4i-a10-ps2";
+		reg = <0x01c2a000 0x400>;
+		interrupts = <0 62 4>;
+		clocks = <&apb1_gates 6>;
+		status = "disabled";
+	};
