gpu: nvgpu: Implement get_rate/set_rate as GPU op

Browse Source 
Move clock APIs from gk20a_platform to gpu_ops. At the same time
allow use of internal get_rate/set_rate for querying both GPCCLK
and PWRCLK on iGPU.

At the same time we can replace calls to clk framework with the
new HAL and drop direct dependency to clk framework.

gp10b ops were replaced as a whole at HAL initialization. That
replaces anything set in platform probe stage, so reduce that to
touch only clock gating regs.
