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.

+Broadcom IPROC SDHCI controller
+
+This file documents differences between the core properties described
+by mmc.txt and the properties that represent the IPROC SDHCI controller.
+
+Required properties:
+- compatible : Should be "brcm,sdhci-iproc-cygnus".
+- clocks : The clock feeding the SDHCI controller.
+
+Optional properties:
+  - sdhci,auto-cmd12: specifies that controller should use auto CMD12.
+
+Example:
+
+sdhci0: sdhci@0x18041000 {
+	compatible = "brcm,sdhci-iproc-cygnus";
+	reg = <0x18041000 0x100>;
+	interrupts = <GIC_SPI 108 IRQ_TYPE_LEVEL_HIGH>;
+	clocks = <&lcpll0_clks BCM_CYGNUS_LCPLL0_SDIO_CLK>;
+	bus-width = <4>;
+	sdhci,auto-cmd12;
+	no-1-8-v;
+};
