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.

+Palmas GPIO controller bindings
+
+Required properties:
+- compatible:
+  - "ti,palams-gpio" for palma series of the GPIO controller
+  - "ti,tps80036-gpio" for Palma series device TPS80036.
+  - "ti,tps65913-gpio" for palma series device TPS65913.
+  - "ti,tps65914-gpio" for palma series device TPS65914.
+- #gpio-cells : Should be two.
+  - first cell is the gpio pin number
+  - second cell is used to specify the gpio polarity:
+      0 = active high
+      1 = active low
+- gpio-controller : Marks the device node as a GPIO controller.
+
+Note: This gpio node will be sub node of palmas node.
+
+Example:
+	palmas: tps65913@58 {
+		:::::::::::
+		palmas_gpio: palmas_gpio {
+			compatible = "ti,palmas-gpio";
+			gpio-controller;
+			#gpio-cells = <2>;
+		};
+		:::::::::::
+	};
