kib f3a84dabad Timeout DMAR commands. ...

Implement timeouts for register-based DMAR commands.  Tunable/sysctl
hw.dmar.timeout specifies the timeout in nanoseconds, set it to zero
to allow infinite wait.  Default is 1ms.

Runtime modification of the sysctl is not safe, it is allowed for
debugging.
