drm/amd/pm: Allow setting max UCLK on SMU v13.0.6

Browse source

Allow reducing max UCLK in MANUAL performance level. New UCLK value
should be less than the max DPM level UCLK level value.

Ex:
echo manual > "/sys/bus/pci/devices/.../power_dpm_force_performance_level"
echo m 1 900 > "/sys/bus/pci/devices/.../pp_od_clk_voltage”
echo c > "/sys/bus/pci/devices/.../pp_od_clk_voltage”
