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.

+Allwinner sun9i USB PHY
+-----------------------
+
+Required properties:
+- compatible : should be one of
+  * allwinner,sun9i-a80-usb-phy
+- reg : a list of offset + length pairs
+- #phy-cells : from the generic phy bindings, must be 0
+- phy_type : "hsic" for HSIC usage;
+	     other values or absence of this property indicates normal USB
+- clocks : phandle + clock specifier for the phy clocks
+- clock-names : depending on the "phy_type" property,
+  * "phy" for normal USB
+  * "hsic_480M", "hsic_12M" for HSIC
+- resets : a list of phandle + reset specifier pairs
+- reset-names : depending on the "phy_type" property,
+  * "phy" for normal USB
+  * "hsic" for HSIC
+
+Optional Properties:
+- phy-supply : from the generic phy bindings, a phandle to a regulator that
+	       provides power to VBUS.
+
+It is recommended to list all clocks and resets available.
+The driver will only use those matching the phy_type.
+
+Example:
+	usbphy1: phy@00a01800 {
+		compatible = "allwinner,sun9i-a80-usb-phy";
+		reg = <0x00a01800 0x4>;
+		clocks = <&usb_phy_clk 2>, <&usb_phy_clk 10>,
+		       <&usb_phy_clk 3>;
+		clock-names = "hsic_480M", "hsic_12M", "phy";
+		resets = <&usb_phy_clk 18>, <&usb_phy_clk 19>;
+		reset-names = "hsic", "phy";
+		status = "disabled";
+		#phy-cells = <0>;
+	};
