x86/ACPI: CPPC: Move init_freq_invariance_cppc() into x86 CPPC
The init_freq_invariance_cppc code actually doesn't need the SMP
functionality. So setting the CONFIG_SMP as the check condition for
init_freq_invariance_cppc may cause the confusion to misunderstand the
CPPC. And the x86 CPPC file is better space to store the CPPC related
functions, while the init_freq_invariance_cppc is out of smpboot, that
means, the CONFIG_SMP won't be mandatory condition any more. And It's more
clear than before.
