platform/x86: intel/pmc: Replace all the reg_map with init functions
The current implementation of pmc core driver has the reg_map assigned
to the CPUID of each platform. Replace the reg_map with init functions
that are defined for each platform.
This is a preparatory patch for redesigning the pmc core driver.
