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

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

+USB Peripheral Controller driver for Aeroflex Gaisler GRUSBDC.
+
+The GRUSBDC USB Device Controller core is available in the GRLIB VHDL
+IP core library.
+
+Note: In the ordinary environment for the core, a Leon SPARC system,
+these properties are built from information in the AMBA plug&play.
+
+Required properties:
+
+- name : Should be "GAISLER_USBDC" or "01_021"
+
+- reg : Address and length of the register set for the device
+
+- interrupts : Interrupt numbers for this device. Either one interrupt number
+	for all interrupts, or one for status related interrupts, one for IN
+	endpoint related interrupts and one for OUT endpoint related interrupts.
+
+Optional properties:
+
+- epobufsizes : Array of buffer sizes for OUT endpoints when they differ
+	from the default size of 1024. The array is indexed by the OUT endpoint
+	number. If the property is present it typically contains one entry for
+	each OUT endpoint of the core. Fewer entries overrides the default sizes
+	only for as many endpoints as the array contains.
+
+- epibufsizes : Array of buffer sizes for IN endpoints when they differ
+	from the default size of 1024. The array is indexed by the IN endpoint
+	number. If the property is present it typically contains one entry for
+	each IN endpoint of the core. Fewer entries overrides the default sizes
+	only for as many endpoints as the array contains.
+
+For further information look in the documentation for the GLIB IP core library:
