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>
Date:   Sat Jul 25 12:13:34 2015 +0200

    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.

+* Renesas CPG DIV6 Clock
+
+The CPG DIV6 clocks are variable factor clocks provided by the Clock Pulse
+Generator (CPG). They clock input is divided by a configurable factor from 1
+to 64.
+
+Required Properties:
+
+  - compatible: Must be one of the following
+    - "renesas,r8a73a4-div6-clock" for R8A73A4 (R-Mobile APE6) DIV6 clocks
+    - "renesas,r8a7740-div6-clock" for R8A7740 (R-Mobile A1) DIV6 clocks
+    - "renesas,r8a7790-div6-clock" for R8A7790 (R-Car H2) DIV6 clocks
+    - "renesas,r8a7791-div6-clock" for R8A7791 (R-Car M2) DIV6 clocks
+    - "renesas,sh73a0-div6-clock" for SH73A0 (SH-Mobile AG5) DIV6 clocks
+    - "renesas,cpg-div6-clock" for generic DIV6 clocks
+  - reg: Base address and length of the memory resource used by the DIV6 clock
+  - clocks: Reference to the parent clock(s); either one, four, or eight
+    clocks must be specified.  For clocks with multiple parents, invalid
+    settings must be specified as "<0>".
+  - #clock-cells: Must be 0
+  - clock-output-names: The name of the clock as a free-form string
+
+
