platform/x86/intel/tpmi: Add additional TPMI header fields

Browse source

TPMI information header added additional fields in version 2. Some of the
reserved fields in version 1 are used to define new fields.

Parse new fields and export as part of platform data. These fields include:
- PCI segment ID
- Partition ID of the package: If a package is represented by more than
  one PCI device, then partition ID along with cdie_mask, describes the
  scope. For example to update get/set properties for a compute die, one
  of the PCI MMIO region is selected from the partition ID.
- cdie_mask: Mask of all compute dies in this partition.
