soc/intel/common: Add CPU Port ID field to GPIO communities

The CPU can have its own Port IDs when addressing GPIO communities, which
differ from the PCH PCR IDs.

1) Add a field to `struct pad_community` that can hold this value when
   known.
2) Add a function to return this value for a given GPIO pad.
