We get tons of cases where the master interrupt handler apparently set
a bit, with the SDEIIR disagreeing. No idea what's going on there, but
it's consistent on gen8+, no one seems to care about it and it's
making CI results flaky.
Shut it up.
No idea what's going on here, but we've had fun with PCH interrupts

regression reports on the mailing lists keep croping up. But no ill
effects have ever been reported. But for paranoia still keep the
message at a debug level as a breadcrumb, just in case.
