gpu: nvgpu: set clk_rate on frequency change
Currently, in gk20a_scale_target, we set clock frequency even if it is equivalent to the rate previously requested by the governor. This change adds a check to bypass this in case new_frequency == prev_frequency. These clocking operations result in multiple BPMP calls, and add significant overhead to submit time. So, we avoid these operations when possible.
