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.

+* NXP LPC32xx SoC USB Device Controller (UDC)
+
+Required properties:
+- compatible: Must be "nxp,lpc3220-udc"
+- reg: Physical base address of the controller and length of memory mapped
+  region.
+- interrupts: The USB interrupts:
+              * USB Device Low Priority Interrupt
+              * USB Device High Priority Interrupt
+              * USB Device DMA Interrupt
+              * External USB Transceiver Interrupt (OTG ATX)
+- transceiver: phandle of the associated ISP1301 device - this is necessary for
+               the UDC controller for connecting to the USB physical layer
+
+Example:
+
+	isp1301: usb-transceiver@2c {
+		compatible = "nxp,isp1301";
+		reg = <0x2c>;
+	};
+
+	usbd@31020000 {
+		compatible = "nxp,lpc3220-udc";
+		reg = <0x31020000 0x300>;
+		interrupt-parent = <&mic>;
+		interrupts = <0x3d 0>, <0x3e 0>, <0x3c 0>, <0x3a 0>;
+		transceiver = <&isp1301>;
+	};
