platform/x86/intel/pmc: Retrieve PMC info only for available PMCs
Update the Intel PMC Core driver to fetch PMC information only for available PMCs. Previously, the driver attempted to retrieve PMC info even when the corresponding PMC was not present. This change aligns with recent updates to the Intel SSRAM Telemetry driver. Starting with NVL, the SSRAM Telemetry driver is probed for each individual SSRAM device. The prior implementation could not differentiate between an unavailable PMC and one that had not yet completed information retrieval. To resolve this, the PMC Core driver now skips obtaining PMC info for unavailable PMCs.
