gpu: nvgpu: ga10b: Set GPU clocks to max rate

Browse Source 
Max GPU clk supported by BPMP is 1.275GHz. Remove the hard-coded
default value of 1GHz and pass an arbitrary high value to BPMP
API to set the clocks to max rate. Use UINT_MAX instead of a
hardcoded clk max_rate value (like 1.275GHz) to ensure that the max
clock rate supported by BPMP is chosen during clk_set_rate().
