platform/x86/intel/tpmi: Get OOBMSM CPU mapping from TPMI
Copy TPMI’s OOBMSM platform info into a common area within VSEC private
data via intel_vsec_set_mapping(). This enables other Intel VSEC features
to access the CPU mapping without additional queries.
Additionally, designate the TPMI driver as a supplier for the Telemetry
driver, ensuring it can obtain the necessary platform information for
future feature extensions.
