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:

    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.

+Kernel driver scx200_acb
+
+Author: Christer Weinigel <wingel@nano-system.com>
+
+The driver supersedes the older, never merged driver named i2c-nscacb.
+
+Module Parameters
+-----------------
+
+* base: up to 4 ints
+  Base addresses for the ACCESS.bus controllers on SCx200 and SC1100 devices
+
+  By default the driver uses two base addresses 0x820 and 0x840.
+  If you want only one base address, specify the second as 0 so as to
+  override this default.
+
+Description
+-----------
+
+Enable the use of the ACCESS.bus controller on the Geode SCx200 and
+SC1100 processors and the CS5535 and CS5536 Geode companion devices.
+
+Device-specific notes
+---------------------
+
+The SC1100 WRAP boards are known to use base addresses 0x810 and 0x820.
+If the scx200_acb driver is built into the kernel, add the following
+parameter to your boot command line:
+  scx200_acb.base=0x810,0x820
+If the scx200_acb driver is built as a module, add the following line to
+a configuration file in /etc/modprobe.d/ instead:
+  options scx200_acb base=0x810,0x820
