kernel-module-imx-gpu-viv: add new package

This is the Vivante kernel driver split from the kernel source code in
order to make it possible to be used in any kernel source since 3.10.53.

The driver source code provided by Freescale needs fixes so the
community forked the code to allow faster development and easier
integration of fixes from the community.

This patch is based on the Yocto equivalent:
https://github.com/Freescale/meta-fsl-arm/commit/32cf391
https://github.com/Freescale/meta-fsl-arm/commit/4249193

This package has been tested with the following commands:
 # modprobe galcore
 # cd /usr/share/examples/viv_samples/vdk/
 # ./tutorial7
