kernel-module-imx-gpu-viv: Fork driver for FSL Community

The driver source code provided by Freescale needs fixes. This fork is
a community driven development and allow faster development and easier
integration of fixes.

The "+fslc" suffix is added to the module during probing to make a
clear identification.

-Subject: [PATCH] kernel-module-imx-gpu-viv: Better work-around for change in name of busfreq-imx.h
-
-The renaming of include/linux/busfreq-imx6.h to include/linux/busfreq-imx.h
-is not consistent over the many kernel versions currently being built.  This
-changeset works around this inconsistency by creating a local symbolic link
-to whatever file is actually present in the kernel sources.
