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:

    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.

+Required properties :
+
+ - compatible : should be "wm,wm8505-i2c"
+ - reg : Offset and length of the register set for the device
+ - interrupts : <IRQ> where IRQ is the interrupt number
+ - clocks : phandle to the I2C clock source
+
+Optional properties :
+
+ - clock-frequency : desired I2C bus clock frequency in Hz.
+	Valid values are 100000 and 400000.
+	Default to 100000 if not specified, or invalid value.
+
+Example :
+
+	i2c_0: i2c@d8280000 {
+		compatible = "wm,wm8505-i2c";
+		reg = <0xd8280000 0x1000>;
+		interrupts = <19>;
+		clocks = <&clki2c0>;
+		clock-frequency = <400000>;
