Same tegra-video.ko can be used for all tegra soc as driver supports 
adding other soc related as well.

Also was thinking instead of renaming media/tegra as media/tegra-vi, 
probably we can rename as media/tegra-video so it will be inline with 
module name we already chosen and also mainly we have vi and csi with in 
that so instead of tegra-vi probably we can use media/tegra-video?
