[PATCH] drm/amd/pm: Reset SMU v13.0.x custom settings

[Lijo Lazar]

On SMU v13.0.2 and SMU v13.0.6 variants user may choose custom min/max
clocks in manual perf mode. Those custom min/max values need to be
reset once user switches to auto or restores default settings.
Otherwise, they may get used inadvertently during the next operation.
