	The Allwinner H6 SoCs use binning in order to provide binning to cpufreq which is supported in Linux, with a matching Device Tree binding. Now that we have the DT validation in place, let's convert the device tree bindings for that controller over to a YAML schemas.

	Allwinner Process Voltage Scaling Tables defines the voltage and frequency value based on the speedbin blown in the efuse combination. The sunxi-cpufreq-nvmem driver reads the efuse value from the SoC to provide the OPP framework with required information. This is used to determine the voltage and frequency value for each OPP of operating-points-v2 table when it is parsed by the OPP framework. The "allwinner,sun50i-h6-operating-points" DT extends the "operating-points-v2" with following parameters: - nvmem-cells (NVMEM area containig the speedbin information) - opp-microvolt-<name>: voltage in micro Volts. At runtime, the platform can pick a <name> and matching opp-microvolt-<name> property.
