drm/radeon/dpm: implement force performance levels for rs780 (v2)
Allows you to limit the selected power levels via sysfs.
Force the feedback divider to select a power level.
v2: fix checking in rs780_force_fbdiv,
drop a duplicate divider structure in rs780_dpm_force_performance_level,
Force the voltage level too.
