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. Tested on J721e-evm for MPU. The series is based on top of the branch: https://github.com/lokeshvutla/u-boot/tree/devel/j721e-full-boot Changes in v3: * Extended the support for j721e-evm. * Moved vtm node under r5-board dts. Changes in v2: * Avoided creation of new uclass. AVS driver is now under misc.
