x86/aperfmperf: Separate AP/BP frequency invariance init
This code is convoluted and because it can be invoked post init via the
ACPI/CPPC code, all of the initialization functionality is built in instead
of being part of init text and init data.
As a first step create separate calls for the boot and the application
processors.
