Version update TEST kernel 4.13.0_next_20170907. Added support for sound for all models S905X and S912.

For some recent images to use these additions, you can only download the kernel and dtb files (deb packages are in the directory TEST\deb) to install in the existing system (don't forget to update the file "dtb.img"
