Some miscellaneous cleanups for the Zalon driver:

 - Remove unused definitions of sync_scsi_data_for_cpu and
   sync_scsi_data_for_device
 - Fill in dev->irq in the zalon driver
 - Request the interrupt in the name of the driver, not the bus address
 - Change the driver name to look better in sysfs
 - Call ncr53c8xx_exit() in zalon7xx_exit()
