perf/x86/intel/uncore: Support per-platform discovery base devices
On DMR platforms, IMH discovery tables are enumerated via PCI, while
CBB domains use MSRs, unlike earlier platforms which relied on either
PCI or MSR exclusively.
DMR also uses different MSRs and PCI devices, requiring support for
multiple, platform-specific discovery bases.
Introduce struct uncore_discovery_domain to hold the discovery base and
other domain-specific configuration.
Move uncore_units_ignore into uncore_discovery_domain so a single
structure can be passed to uncore_discovery_[pci/msr].
No functional change intended.
