description:
Make sure interrupts are disabled during cpu_configure(9).
Fixes 'panic: kernel diagnostic assertion "cv_is_valid(cv)" failed'
during fdcisa(4) probe on Milan's DIAGNOSTIC kernel, caused by
a stray interrupt from the FDC right after isa_intr_establish().
No visible bad side effect on TT030 with this change.
Should be pulled up to netbsd-8.
