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.
