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.

+* Two Wire Serial Interface (TWSI) / I2C

+- compatible: "cavium,octeon-3860-twsi"
+
+  Compatibility with all cn3XXX, cn5XXX and cn6XXX SOCs.
+
+- reg: The base address of the TWSI/I2C bus controller register bank.
+
+- #address-cells: Must be <1>.
+
+- #size-cells: Must be <0>.  I2C addresses have no size component.

+- interrupts: A single interrupt specifier.

+- clock-frequency: The I2C bus clock rate in Hz.
