perf/x86/uncore: Ignore broken units in discovery table
Some units in a discovery table may be broken, e.g., UPI of SPR MCC.
A generic method is required to ignore the broken units.
Add uncore_units_ignore in the struct intel_uncore_init_fun, which
indicates the type ID of broken units. It will be assigned by the
platform-specific code later when the platform has a broken discovery
table.
