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.

+Binding for Texas Instruments DPLL clock.
+
+Binding status: Unstable - ABI compatibility may be broken in the future
+
+This binding uses the common clock binding[1].  It assumes a
+register-mapped DPLL with usually two selectable input clocks
+(reference clock and bypass clock), with digital phase locked
+loop logic for multiplying the input clock to a desired output
+clock. This clock also typically supports different operation
+modes (locked, low power stop etc.) This binding has several
+sub-types, which effectively result in slightly different setup
+for the actual DPLL clock.
+
+[1] Documentation/devicetree/bindings/clock/clock-bindings.txt
+
+Required properties:
+- compatible : shall be one of:
+		"ti,omap3-dpll-clock",
+		"ti,omap3-dpll-core-clock",
+		"ti,omap3-dpll-per-clock",
+		"ti,omap3-dpll-per-j-type-clock",
+		"ti,omap4-dpll-clock",
+		"ti,omap4-dpll-x2-clock",
+		"ti,omap4-dpll-core-clock",
+		"ti,omap4-dpll-m4xen-clock",
+		"ti,omap4-dpll-j-type-clock",
+		"ti,omap5-mpu-dpll-clock",
+		"ti,am3-dpll-no-gate-clock",
+		"ti,am3-dpll-j-type-clock",
+		"ti,am3-dpll-no-gate-j-type-clock",
+		"ti,am3-dpll-clock",
+		"ti,am3-dpll-core-clock",
+		"ti,am3-dpll-x2-clock",
+		"ti,omap2-dpll-core-clock",
+
+- #clock-cells : from common clock binding; shall be set to 0.
+- clocks : link phandles of parent clocks, first entry lists reference clock
+  and second entry bypass clock
+- reg : offsets for the register set for controlling the DPLL.
+  Registers are listed in following order:
+	"control" - contains the control register base address
+	"idlest" - contains the idle status register base address
+	"mult-div1" - contains the multiplier / divider register base address
+	"autoidle" - contains the autoidle register base address (optional)
+  ti,am3-* dpll types do not have autoidle register
+  ti,omap2-* dpll type does not support idlest / autoidle registers
+
+Optional properties:
+- DPLL mode setting - defining any one or more of the following overrides
+  default setting.
+	- ti,low-power-stop : DPLL supports low power stop mode, gating output
+	- ti,low-power-bypass : DPLL output matches rate of parent bypass clock
+	- ti,lock : DPLL locks in programmed rate
+
