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.
For the entire series:

Tom,
If no further comments can this series be pulled in?

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.
