In the !x86_match_cpu() fallback path, has_generic_discovery_table() is removed because it does not handle multiple PCI devices. Instead, use PCI_ANY_ID in generic_uncore_init[] to probe all PCI devices. For MSR portals, only probe MSR 0x201e to keep the fallback simple, as this path is best-effort only.
