Wouldn't this also disturb the existing cpufreq driver for earlier
tegra platforms? i.e. we don't need cpufreq-cpu0 for them
atleast as of now.

Perhaps this should be "select" rather than "depends on"?

Shouldn't we do a of_node_get() here?

I think this would need to be get_device() since it's the struct device
that's being used subsequently.
