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

    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.

+Texas Instruments TWL family (twl4030) reset and power management module
+
+The power management module inside the TWL family provides several facilities
+to control the power resources, including power scripts. For now, the
+binding only supports the complete shutdown of the system after poweroff.
+
+Required properties:
+- compatible : must be one of the following
+	"ti,twl4030-power"
+	"ti,twl4030-power-reset"
+	"ti,twl4030-power-idle"
+	"ti,twl4030-power-idle-osc-off"
+
+The use of ti,twl4030-power-reset is recommended at least on
+3530 that needs a special configuration for warm reset to work.
+
+When using ti,twl4030-power-idle, the TI recommended configuration
+for idle modes is loaded to the tlw4030 PMIC.
+
+When using ti,twl4030-power-idle-osc-off, the TI recommended
+configuration is used with the external oscillator being shut
+down during off-idle. Note that this does not work on all boards
+depending on how the external oscillator is wired.
+
+Optional properties:
+
+- ti,system-power-controller: This indicates that TWL4030 is the
+  power supply master of the system. With this flag, the chip will
+  initiate an ACTIVE-to-OFF or SLEEP-to-OFF transition when the
+  system poweroffs.
+
+- ti,use_poweroff: Deprecated name for ti,system-power-controller
+
+Example:
+&i2c1 {
+	clock-frequency = <2600000>;
+
+	twl: twl@48 {
+		reg = <0x48>;
+		interrupts = <7>; /* SYS_NIRQ cascaded to intc */
+		interrupt-parent = <&intc>;
+
+		twl_power: power {
+			compatible = "ti,twl4030-power";
+			ti,use_poweroff;
+		};
+	};
+};
