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.

+TI Real Time Clock
+
+Required properties:
+- compatible:
+	- "ti,da830-rtc"  - for RTC IP used similar to that on DA8xx SoC family.
+	- "ti,am3352-rtc" - for RTC IP used similar to that on AM335x SoC family.
+			    This RTC IP has special WAKE-EN Register to enable
+			    Wakeup generation for event Alarm. It can also be
+			    used to control an external PMIC via the
+			    pmic_power_en pin.
+- reg: Address range of rtc register set
+- interrupts: rtc timer, alarm interrupts in order
+- interrupt-parent: phandle for the interrupt controller
+
+Optional properties:
+- system-power-controller: whether the rtc is controlling the system power
+  through pmic_power_en
+
+Example:
+
+rtc@1c23000 {
+	compatible = "ti,da830-rtc";
+	reg = <0x23000 0x1000>;
+	interrupts = <19
+		      19>;
+	interrupt-parent = <&intc>;
+	system-power-controller;
+};
