structure of driver is based on prior feedback.

How about instead of re-structuring whole driver again, probably we can 
use conditional compatibles and also corresponding tegra210.o in 
Makefile based on ARCH_TEGRA?

#if defined(CONFIG_ARCH_TEGRA_210_SOC)
ÂÂÂ { .compatible = "nvidia,tegra210-vi", .data = &tegra210_vi_soc },
#endif
