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

+Altera Timer
+
+Required properties:
+
+- compatible : should be "altr,timer-1.0"
+- reg : Specifies base physical address and size of the registers.
+- interrupt-parent: phandle of the interrupt controller
+- interrupts : Should contain the timer interrupt number
+- clock-frequency : The frequency of the clock that drives the counter, in Hz.
+
+Example:
+
+timer {
+	compatible = "altr,timer-1.0";
+	reg = <0x00400000 0x00000020>;
+	interrupt-parent = <&cpu>;
+	interrupts = <11>;
+	clock-frequency = <125000000>;
