xdriver_xf86-video-imx-viv: new package

Xorg driver for imx6. Inspired from Yocto project.

I did not find any problem, but notice Yocto project force Xorg xserver
1.14.4 while we use 1.16.

Notice Vivante driver should be able to provide Desktop OpenGL implementation.
However, this feature seems broken for a while[1]. Yocto use Mesa3D/swraster
to provide Desktop OpenGL API[2].

Tested with:
    subsequent qt5base and libdrm fixes +
