soc/intel/common: Implement ACPI CPPCv3 package to support hybrid core

The patch implements ACPI CPPCv3 package. It implements and updates the
following methods:

generate_cppc_entries(): Updates method to support CPPCv3 package

acpigen_write_CPPC_hybrid_method(): It generates ACPI code to implement
_CPC method and calls XPPPC method.

acpi_write_xppc_method(): It generates ACPI code if cpu supports
Nominal Frequency. It generates ACPI code which sets Nominal Frequency
and updates Nominal Performance. It uses below calculation to update
the Nominal Frequency and Nominal Performance:
        Nominal Frequency = Max non-turbo ratio * cpu_bus_frequency
        Nominal Performance = Max non-turn ratio * cpu scaling factor

CPU scaling factor varies in the hybrid core environment. So, the
generated ACPI code updates Nominal Performance based on the CPU's
scaling factor.

TEST=Verified CPPCv3 package and XPP3 method are getting created in the
SSDT table.
