thorpej 6f1701b01c Put a lock on the pcic, to serialize access to the chip during event
handling.  This is important when multiple cards are present when
the system boots, as we use tsleep now instead of delay in various
places (delay used to provide serialization by virtue of not causing
a context switch).
