[PATCH] sym2 version 2.1.18n

sym2 version 2.1.18n:
 - Prevent querying for DT clocking on a single ended bus
 - Check the U3EN bit instead of the ULTRA3 bit
 - Only use PPR if SDTR is incapable of negotiating the desired options or
   speed
 - minsync bugfix (James Bottomley)
 - Always calculate what negotiation to perform inside sym_prepare_nego()
 - Delete unused SYM_OPT_HANDLE_IO_TIMEOUT and SYM_CONF_TIMEOUT_ORDER_MAX
   code (Christoph Hellwig)
 - Use SCSI-3 message names instead of SCSI-2 names
 - Remove private definitions of PCI IDs
 - Reorganise DMA mask setup
 - Fix comment tpyo
 - Make some needlessly global code static (Adrian Bunk)
 - Reorder some functions to eliminate predeclaration
 - Use memset instead of bzero
 - Consolidate and abstract SPARC's special IRQ printing
 - Convert hcb_p to struct sym_hcb *
 - Remove cam_ccb_p and cam_scsiio_p typedefs
 - Treat PA-RISC firmware as if it were a type of NVRAM

- *  It uses a power-of-two based algorithm of my own:) 
- *  that avoids scanning of lists, provided that:
- *
- *  - The IO does complete in less than half the associated
- *    timeout value.

- *  For example, if tick is 1 second and the max order is 8,

- *  just be put into some list at queuing and be removed
