Adaptive Voltage Scaling is a technology used in TI SoCs to optimize the operating voltage based on characterization data written to efuse during production.
Add support for Adaptive Voltage scaling class 0 support for AM6 family of devices. Adaptive voltage scaling class 0 implies that optimized voltage values for a particular OPP of a particular voltage domain are read from Efuse and programmed on the pmic/regulator.
Tested on AM654-EVM for MPU @800 MHz.
