perf/x86/intel/uncore: Remove has_generic_discovery_table()

Browse source

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.
