Previously, the address regions described by disabled admatch entries would be treated as being mapped to the given core; while incorrect, this was essentially harmless given that the entries describe unused address space on the few affected devices. We now perform parsing of per-core admatch registers and interrupt flags in siba_erom, correctly skip any disabled admatch entries, and use the siba_erom API in siba_add_children() to perform enumeration of attached cores.
