gpu: nvgpu: support for clk.measure_freq for igpu

Browse Source 
Add support for the measure_freq clock op for igpu:
  - add nvgpu_clk_measure_freq(), which in turn calls
    the get_rate() clock op.
  - Initialize the measure_freq clock op to nvgpu_clk_measure_freq()
    for native linux and vgpu.
