- Use the per-instance device lock instead of Giant for the CAM sim lock.
- Add global locks to protect the adapter list and DPC queues.
- Use wakeup() and mtx_sleep() to wait for certain events like the
controller going idle rather than polling via timeouts passed to
tsleep().
- Use callout(9) instead of timeout(9).
- Mark the interrupt handler MPSAFE.
