Patch 423e9e0fc0: Documentation/lint: Use Super I/O instead of SuperIO
added the word SuperIO to the checkpatch spelling list.
There were unfortunately some issues with this.
1) This introduced a problem because the comparison is used in different
cases in different places. The misspelled word is compared ignoring
the case, but when looking for the correct word, it looks through the
list for the misspelling in all lowercase. When it couldn't find the
word "superio" in the list, the variable came back uninitialized.
2) The spellcheck feature isn't enabled in checkpatch unless the option
--strict is enabled, so this wasn't getting reported anyway.
3) SuperIO (or superio) will match the KCONFIG options such as
CONFIG_SUPERIO_NUVOTON_NCT5104D, and suggest "Super I/O" which doesn't
make any sense.

The patch defines the following helper functions:
get_cpu_scaling_factor(): Returns scaling factors of big and small core.
cpu_is_nominal_freq_supported(): Returns true if CPU supports Nominal
Frequency, otherwise false.
cpu_is_nominal_freq_supported(): Check CPU supports nominal frequency or
not.
The patch also enables CPPCv3 support for Intel Alder Lake which is
based on hybrid core architecture.
TEST=Verified Nominal Frequency and Nominal Performance are getting
updated for ADL-P small and big cores correctly.

The patch implements ACPI CPPCv3 package. It implements and updates the
following methods:
generate_cppc_entries(): Updates method to support CPPCv3 package
acpi_get_cpu_nominal_freq(): Calculates CPU's nominal frequency
acpi_get_cpu_nomi_perf(): Calculates nominal performance for big and
small cores.
acpigen_write_CPPC_hybrid_method(): It generates ACPI code to implement
_CPC method.
acpigen_cppc_update_nominal_freq_perf(): It updates CPPC3 package 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 is getting created in the SSDT table.

Don't assume that libpayload is built from a fully checked
out coreboot tree.
There's already an override when building vboot, so reuse
that override when referring to its header files.
