kernel - Run AHCI and SILI disk drivers MPSAFE
* These drivers now pass a port-disk-port lock in the cam sim registration,
which should result in CAM callbacks being MPSAFE.
* Add a separate signalling interlock for the port threads.
* The devices were otherwise already MPSAFE, with per-port locking.
