Darrick J. Wong 3b709df5f7 [SCSI] aic94xx: Fix DDB and SCB initialization 
Ed Chim of Adaptec informs us that the DDB registers need to be zeroed at
initialization time and that some SCB initializations need to happen even if
we don't use the SCB.

* TU - Task Unacked, command was transmitted but neither ACK (R_OK) nor NAK
* (R_ERR) was received due to loss of signal, broken connection, loss of
* dword sync or other reason. The application client should send the
* appropriate task query.
* TA - Task Aborted, see TF.
* _RESP - The completion includes an empty buffer containing status.
* TO - Timeout.
