platform/x86:intel/pmc: Create generic_core_init() for all platforms
Create a generic_core_init() function for all architectures to reduce
duplicate code in each architecture file. Create an info structure
to catch the variations between each architecture and pass it to the
generic init function.
Convert all architectures to call the generic core init function.
