When there are sufficiently many devices listed in the ACPI tables (no
matter if they actually exist), output may take way longer than the
watchdog would like.

TBD: Seeing the volume of output I wonder whether we should further
suppress logging headers of devices which have no active entry
(i.e. emit the header only upon finding the first IRTE worth
logging). And while minor for the total volume of output I'm
also unconvinced logging both a "per device" header line and a
"shared" one makes sense, when only one of the two can actually
be followed by actual contents.
