The DA6021 outputs DISA, DISB, DISCRIT are directly derived from the current platform status and the register
settings.
The PROCCHOT_B signal is derived from a several input criterias as DA6021 on-die, battery and system
temperature as well as battery voltage drop. In order to make decision, the corresponding result registers on the
ADC side will be accessible (in static way) for reading from the SVTM.
