Add support to read the voltage look up table and populate OPP for all
corresponding CPUS for consumers like the energy model could use the
frequency and voltage from the OPP tables. Also update the logic to not add
duplicate OPPs.

subsys_initcall causes problems registering the driver as a thermal
cooling device.
If "faster boot" is the main reason for doing subsys_initcall, this
should be handled in the bootloader or another boot constraint
framework.

The CPUfreq HW present in some QCOM chipsets offloads the steps necessary
for changing the frequency of CPUs. The driver implements the cpufreq
driver interface for this hardware engine.
