drm/amd/pp: Refine get_gpu_power for VI
pkgpwr is the average gpu power of 100ms. it is calculated by
firmware in real time.
1. we can send smu message PPSMC_MSG_GetCurrPkgPwr to read currentpkgpwr directly.
2. On Fiji/tonga/bonaire/hawwii, without PPSMC_MSG_GetCurrPkgPwr support.
Send PPSMC_MSG_PmStatusLogStart/Sample to let smu write currentpkgpwr
to ixSMU_PM_STATUS_94. driver can read pkgpwr from ixSMU_PM_STATUS_94.
