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.
