  While most bridges can bring a card out of reset in 20ms, there are
  some bridge + card combinations that take longer for reasons unknown.
  Adjust the timeout to be 100ms on all !RICOH bridges, but leave RICOH
  at 400ms.  The 400ms is "lore" from other open source projects, and
  I've never see my ricoh bridge chips take this long.  Maybe it is the
  same thing?  Maybe a bit should be read instead of a hard-wired pause?
  
  After this adjustment, a few cards that I'd insert and get only:
          cbb0: card_power: 3V
          cbb0: card_power: 0V
  with full debugging enabled would actually try to attach.
