New GPU sysfs Power State Interface for custom pp_od_clk_voltage

Description

In order to use a custom pp_od_clk_voltage one has to set power_dpm_force_performance_level to manual.

However this way it is not possible to use custom pp_od_clk_voltage and force - for instance - high or peak performance levels.


The forcing of different performance levels doesn't (and shouldn't) relate to custom clocks/voltages. Putting this setting in the same interface is a poor choice and (unnecessarily) restricts the possibilities.


Please add a new sysfs interface for solely choosing between default and custom pp_od_clk_voltage.
