Warner Losh e4e7b5bc54 Add two of three workarounds for interrupt storms for o2micro parts as
obtained from o2micro.  These should only be needed for 'older'
o2micro bridges (anything before the 7xxx series of bridges), but will
work with the new bridges.

# I don't plan on porting it to oldcard, but will happily commit to
# oldcard if someone else needs them.

* Mask of allowable interrupts.

* For IBM-AT machines, irqs 3, 4, 5, 7, 9, 10, 11, 12, 14, 15 are
* allowed. Nearly all IBM-AT machines with pcic cards or bridges
* wire these interrupts (or a subset thereof) to the corresponding
* pins on the ISA bus. Some older laptops are reported to not route
* all the interrupt pins to the bus because the designers knew that
* some would conflict with builtin devices. Older versions of Windows
* NT had a special device that would probe for conflicts early in the
* boot process and formulate a mapping table. Maybe we should do
* something similar.
*
* For NEC PC-98 machines, irq 3, 5, 6, 9, 10, 11, 12, 13 are allowed.
* These correspond to the C-BUS signals INT 0, 1, 2, 3, 41, 42, 5, 6
* respectively.

* Hiroshi TSUKADA-san writes in FreeBSD98-testers that CBUS INT 2

* cbus add-in cards. He has confirmed this routing with a visual
