gpu: nvgpu: Rename clk->get_rate to measure_freq

get_rate is already used for call-back that queries the last set
clock rate. This instance of get_rate actually measures the frequency
so renaming it to measure_freq.

At the same time modify to use hertz instead of megahertz. We use
fractional megahertz already in GPU.
