drm/amd/pm: reverse mclk and fclk clocks levels for renoir
commit 55e02c14f9b5fd973ba32a16a715baa42617f9c6 upstream.

This patch reverses the DPM clocks levels output of pp_dpm_mclk
and pp_dpm_fclk for renoir.

On dGPUs and older APUs we expose the levels from lowest clocks
to highest clocks. But for some APUs, the clocks levels 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.
