- Add a new quirk to indicate that pin 0 of the first I/O APIC is really
IRQ 0 and not an ExtINT pin. The MADT enumerators ignore the PC-AT flag
and ignore overrides that map IRQ 0 to pin 2 when this quirk is present.
- Add a block comment above the quirks to document each quirk so that we
can use more verbose descriptions quirks.
