Allow qcom-hw driver to initialize right after the cpufreq and thermal
subsystems are initialised in core_initcall so we get earlier access to
thermal mitigation.

Add calls to arch_set_freq_scale() in qcom-cpufreq-hw driver to enable
frequency invariance.

The core count read back from the each domain's look up table serves
as an indicator for the onset of the turbo frequency and not accurate
representation of number of cores in a paticular domain. Update turbo
detection logic accordingly to add support for SM8150 SoCs.

Try and register an Energy Model from qcom-cpufreq-hw to allow
interested sub-systems like the task scheduler to use the provided
information.

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.

Add the CPUFREQ_IS_COOLING_DEV flag to allow the cpufreq core to
auto-register the driver as a cooling device.

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.
