[SCSI] aic94xx: plumb in I_T_nexus_reset task management function
Currently aic94xx has no exported I_T_nexus_reset function. This is a bit of a huge problem, since sas_ata relies on this function to perform an ATA phy reset and also it means that if abort fails, we really have no bigger hammer to hit everything with. Plumb in the I_T_nexus_reset by quiescing the sequencer, sending the correct phy reset (link for ATA and hard for SAS) and then carefully resuming the sequencer again.
