Nick Cheng 36b83ded06 [SCSI] arcmsr: Support HW reset for EH and polling scheme for scsi device 
1. To support instantaneous report for SCSI device existing by periodic
   polling
2. In arcmsr_iop_xfer(), inform AP of F/W's deadlock state to prevent
   endless waiting
3. To block the coming SCSI command while the driver is handling bus reset
4. To support HW reset in bus reset error handler
