Revert r330897:

This was intended to be a non-functional change. It wasn't. The commit
message was thus wrong. In addition it broke arm, and merged crypto
related code.

Revert with prejudice.

This revert skips files touched in r316370 since that commit was since
MFCed. This revert also skips files that require $FreeBSD$ property
changes.

Thank you to those who helped me get out of this mess including but not
limited to gonzo, kevans, rgrimes.

Various fixes to hptmv(4):
- Replace the global driver lock with a per-instance device lock.
- 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.
- Remove compat shims for FreeBSD versions older than 8.0.
