Log message:
dapmic(4): support clean shutdown with the power button
Register an interrupt handler and look for nONKEY events.
Mask off all other events. Also clear the FAULT_LOG register at
startup, but don't attempt to acknowledge its contents at runtime. This
lets the user force a shutdown with a long power button press. Some
events in EVENT_* or FAULT_LOG may benefit from more graceful handling.
This makes it possible to cleanly shutdown my Hifive Unmatched using
the power button.
Thanks to kettenis@ who wrote sfgpio(4) to handle dapmic(4) interrupts
on the Unmatched. ok kettenis@
