Yes, that name is better.

I wondered about that, and thought it'd be odd for e.g. Tegra114 clock
code to be calling Tegra30 functions. That said, if we start encoding
into function names a complete description of which chips they support,
we'll have very long function names, so I guess renaming it makes sense.
I'll post V3.
