Do not ever try to coredump adapter memory regions.
PR: 4486
Submitted by: tegge@idi.ntnu.no (Tor Egge)
Implement a function is_adapter_memory() in order to determine what
should nto be dumped at all. Currently, only populated with the ``ISA
memory hole''. Adapter regions of other busses should be added.
