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

We lose all the git history this way and it's not good. We
should apply another opnfv project repo in future.

+TI EDMA
+
+Required properties:
+- compatible : "ti,edma3"
+- #dma-cells: Should be set to <1>
+              Clients should use a single channel number per DMA request.
+- reg: Memory map for accessing module
+- interrupt-parent: Interrupt controller the interrupt is routed through
+- interrupts: Exactly 3 interrupts need to be specified in the order:
+              1. Transfer completion interrupt.
+              2. Memory protection interrupt.
+              3. Error interrupt.
+Optional properties:
+- ti,hwmods: Name of the hwmods associated to the EDMA
+- ti,edma-xbar-event-map: Crossbar event to channel map
+
+Deprecated properties:
+Listed here in case one wants to boot an old kernel with new DTB. These
+properties might need to be added to the new DTS files.
+- ti,edma-regions: Number of regions
+- ti,edma-slots: Number of slots
+- dma-channels: Specify total DMA channels per CC
+
+Example:
+
+edma: edma@49000000 {
+	reg = <0x49000000 0x10000>;
+	interrupt-parent = <&intc>;
+	interrupts = <12 13 14>;
+	compatible = "ti,edma3";
+	ti,hwmods = "tpcc", "tptc0", "tptc1", "tptc2";
+	#dma-cells = <1>;
+	ti,edma-xbar-event-map = /bits/ 16 <1 12
+					    2 13>;
+};
