[SCSI] advansys: Changes to work on parisc

Change PortAddr to be an unsigned int instead of an unsigned short (IO
Port address are 24 bit on parisc).  Fix a couple of printk argument
warnings.  Remove the Kconfig marking as 'BROKEN'.

I haven't removed the #warning yet because virt_to_bus/bus_to_virt are
only eliminated for narrow boards.  Wide boards need more work.
