Properly account for the possibility of several frequencies having the
same voltage dependency. When changing the core voltages the voltage
dependencies in the OPP of L3, GPU, FDIF and HSI are adjusted. When
changing the IVA voltages the voltage dependencies in the OPP of IVA,
DSP and AESS are adjusted.
