Do we actually need this clock upstream yet?

IIRC, Prashant was working on implementing the common reset API, so I'd
prefer not to add any reset-only "clocks" to the clock driver, but
rather to simply make sure that the new reset driver exposes them.

To make this change, you would also need to edit
include/dt-bindings/clock/tegra114-car.h. BTW, why doesn't the Tegra
clock driver include that file rather than defining its own enum?
