As a part of refactoring, we need to move the volt unit from perf to pmu as it belongs there and also move the arbitor specific functions under CLK_ARB as they will be removed from safety build. This patch does the following *Move volt struct from perf to pmu *Move volt setup from pmu_pstate to volt *Move clk freq related functions into CLK_ARB NVGPU-4491 NVGPU-4492 Change-Id: I7180cd12bbf91cc4d2e79b6e2d71c16e494c8ff0 Signed-off-by: Abdul Salam <absalam@nvidia.com> Reviewed-on: https://git-master.nvidia.com/r/2268215 Reviewed-by: Deepak Nibade <dnibade@nvidia.com> Reviewed-by: mobile promotions <svcmobile_promotions@nvidia.com> Tested-by: mobile promotions <svcmobile_promotions@nvidia.com>
