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.

+charger-manager bindings
+~~~~~~~~~~~~~~~~~~~~~~~~
+
+Required properties :
+ - compatible : "charger-manager"
+ - <>-supply : for regulator consumer
+ - cm-num-chargers : number of chargers
+ - cm-chargers : name of chargers
+ - cm-fuel-gauge : name of battery fuel gauge
+ - subnode <regulator> :
+	- cm-regulator-name : name of charger regulator
+	- subnode <cable> :
+		- cm-cable-name : name of charger cable
+		- cm-cable-extcon : name of extcon dev
+(optional)	- cm-cable-min : minimum current of cable
+(optional)	- cm-cable-max : maximum current of cable
+
+Optional properties :
+ - cm-name : charger manager's name (default : "battery")
+ - cm-poll-mode : polling mode (enum polling_modes)
+ - cm-poll-interval : polling interval
+ - cm-battery-stat : battery status (enum data_source)
+ - cm-fullbatt-* : data for full battery checking
+ - cm-thermal-zone : name of external thermometer's thermal zone
+ - cm-battery-* : threshold battery temperature for charging
+	-cold : critical cold temperature of battery for charging
+	-cold-in-minus : flag that cold temperature is in minus degrees
+	-hot : critical hot temperature of battery for charging
+	-temp-diff : temperature difference to allow recharging
+ - cm-dis/charging-max = limits of charging duration
+
+Example :
+	charger-manager@0 {
+		compatible = "charger-manager";
