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.

+* Renesas USB DMA Controller Device Tree bindings
+
+Required Properties:
+- compatible: must contain "renesas,usb-dmac"
+- reg: base address and length of the registers block for the DMAC
+- interrupts: interrupt specifiers for the DMAC, one for each entry in
+  interrupt-names.
+- interrupt-names: one entry per channel, named "ch%u", where %u is the
+  channel number ranging from zero to the number of channels minus one.
+- clocks: a list of phandle + clock-specifier pairs.
+- #dma-cells: must be <1>, the cell specifies the channel number of the DMAC
+  port connected to the DMA client.
+- dma-channels: number of DMA channels
+
+Example: R8A7790 (R-Car H2) USB-DMACs
