Merge from FreeBSD-4, revision 188.8.131.52:
Pin 0 on the first I/O APIC is always an ExtINT pin. Some BIOS's are
broken and list the type of the pin as INT rather than ExtINT in the MP
Table. To workaround, force pin 0 of ioapic 0 to be ExtINT if it is of
type INT. This is not a MFC as -current has very different apic code now.
Current's mptable parser might need a similar workaround.
This fixes a bunch of Fujitsu machines; more information about the problem
