This short series aims to make platform-specific parts of cpufreq optional
and dependant on INTEL & AMD config options. This is to allow for tuning
the build for either AMD or Intel platform exclusively and hence to drop
the code that would be left unused.

The initial v1 patch has been extended to not only cover HWP & Powernow
drivers, but additionally ACPI driver is moved outside of cpufreq generic code
and as Intel-dependant piece is put under CONFIG_INTEL option.

Patch v1 & related discussion are here:
