drm/amd/pm: reverse mclk and fclk clocks levels for vangogh
This patch reverses the DPM clocks levels output of pp_dpm_mclk and pp_dpm_fclk. On dGPUs and older APUs we expose the levels from lowest clocks to highest clocks. But for some APUs, the clocks levels that from the DFPstateTable are given the reversed orders by PMFW. Like the memory DPM clocks that are exposed by pp_dpm_mclk. It's not intuitive that they are reversed on these APUs. All tools and software that talks to the driver then has to know different ways to interpret the data depending on the asic. So we need to reverse them to expose the clocks levels from the driver consistently.
