xdriver_xf86-video-imx-viv: bump version to 5.0.11.p8.6

This patch is based on the Yocto equivalent:
https://github.com/Freescale/meta-freescale/commit/0c40332c

The following xorg.conf was used in order to force the use of the
vivante module:
https://github.com/Freescale/meta-fsl-arm/blob/master/recipes-graphics/xorg-xserver/xserver-xf86-config/mx6/xorg.conf

Note that the X server must be started with the "noreset" option to
avoid crashes when closing X apps.
Tested with:
 # X -noreset &
 # cd /usr/share/examples/viv_samples/vdk/
 # DISPLAY=:0 ./tutorial7
