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>
Date:   Sat Jul 25 12:13:34 2015 +0200

    Prepare v4.1.3-rt3

    Signed-off-by: Sebastian Andrzej Siewior <bigeasy@linutronix.de>

We lose all the git history this way and it's not good. We
should apply another opnfv project repo in future.

+	  The Hammerhead platform is built around an AVR32 32-bit microcontroller from Atmel.
+	  It offers versatile peripherals, such as ethernet, usb device, usb host etc.
+
+	  The board also incorporates a power supply and is a Power over Ethernet (PoE) Powered
+	  Device (PD).
+
+	  Additionally, a Cyclone III FPGA from Altera is integrated on the board. The FPGA is
+	  mapped into the 32-bit AVR memory bus. The FPGA offers two DDR2 SDRAM interfaces, which
+	  will cover even the most exceptional need of memory bandwidth. Together with the onboard
+	  video decoder the board is ready for video processing.
