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.

+* Rohm BU21013 Touch Screen
+
+Required properties:
+ - compatible              : "rohm,bu21013_tp"
+ - reg                     :  I2C device address
+
+Optional properties:
+ - touch-gpio              : GPIO pin registering a touch event
+ - <supply_name>-supply    : Phandle to a regulator supply
+ - rohm,touch-max-x        : Maximum outward permitted limit in the X axis
+ - rohm,touch-max-y        : Maximum outward permitted limit in the Y axis
+ - rohm,flip-x             : Flip touch coordinates on the X axis
+ - rohm,flip-y             : Flip touch coordinates on the Y axis
+
+Example:
+
+	i2c@80110000 {
+		bu21013_tp@0x5c {
+			compatible = "rohm,bu21013_tp";
+			reg = <0x5c>;
+			touch-gpio = <&gpio2 20 0x4>;
+			avdd-supply = <&ab8500_ldo_aux1_reg>;
+
+			rohm,touch-max-x = <384>;
+			rohm,touch-max-y = <704>;
+			rohm,flip-y;
