  Clear pending interrupts before we enable external interrupts.
  Recently the AP in my Merced box seems to have grown a habit
  of getting unexpected interrupts, such as redundant wake-ups
  and legacy interrupts that require an INTA cycle.
  While here, replace DELAY(0) with cpu_spinwait() so that it's
  clear what we're doing as well as enable the code to take
  advantage of cpu_spinwait() when it gets implemented.
