As a part of refactoring, we need to move the volt functions from pmu_pstate.c to volt.c 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 setup from pmu_pstate to volt *Move clk freq related functions into CLK_ARB *Replace pmu.h with nvgpu_mem.h in boardobj.h *Rename obj_volt to nvgpu_pmu_volt NVGPU-4491 NVGPU-4492 Change-Id: I9abc96f695fce41893311982a80dc3656aaa64d6 Signed-off-by: Abdul Salam <absalam@nvidia.com> Reviewed-on: https://git-master.nvidia.com/r/c/linux-nvgpu/+/2282361 Reviewed-by: Ramesh Mylavarapu <rmylavarapu@nvidia.com> Reviewed-by: Vaibhav Kachore <vkachore@nvidia.com> Reviewed-by: mobile promotions <svcmobile_promotions@nvidia.com> Tested-by: mobile promotions <svcmobile_promotions@nvidia.com> GVS: Gerrit_Virtual_Submit
