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.

+	  Say Y here if your system has a dual role high speed USB
+	  controller based on the Mentor Graphics silicon IP.  Then
+	  configure options to match your silicon and the board
+	  it's being used with, including the USB peripheral role,
+	  or the USB host role, or both.
+
+	  Texas Instruments families using this IP include DaVinci
+	  (35x, 644x ...), OMAP 243x, OMAP 3, and TUSB 6010.
+
+	  Analog Devices parts using this IP include Blackfin BF54x,
+	  BF525 and BF527.
+
+	  If you do not know what this is, please say N.
+
+	  To compile this driver as a module, choose M here; the
+	  module will be called "musb-hdrc".
