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.

+* Samsung AHCI SATA Controller
+
+SATA nodes are defined to describe on-chip Serial ATA controllers.
+Each SATA controller should have its own node.
+
+Required properties:
+- compatible		: compatible list, contains "samsung,exynos5-sata"
+- interrupts		: <interrupt mapping for SATA IRQ>
+- reg			: <registers mapping>
+- samsung,sata-freq	: <frequency in MHz>
+- phys			: Must contain exactly one entry as specified
+			  in phy-bindings.txt
+- phy-names		: Must be "sata-phy"
+
+Optional properties:
+- clocks		: Must contain an entry for each entry in clock-names.
+- clock-names		: Shall be "sata" for the external SATA bus clock,
+			  and "sclk_sata" for the internal controller clock.
+
+Example:
+	sata@122f0000 {
+		compatible = "snps,dwc-ahci";
+		samsung,sata-freq = <66>;
+		reg = <0x122f0000 0x1ff>;
+		interrupts = <0 115 0>;
+		clocks = <&clock 277>, <&clock 143>;
+		clock-names = "sata", "sclk_sata";
+		phys = <&sata_phy>;
+		phy-names = "sata-phy";
+	};
