Log:
  Do not attach children of owc_gpiobus until interrupts are working.
  
  The children of the bus need to do IO on the bus to probe for hardware
  presence.  Doing IO means timing the bus states using sbinuptime(), and
  that requires working timecounters, which are not initialized until after
  device attachment has completed.
