[SCSI] sym2 version 2.2.1

sym2 version 2.2.1:
 - Fix MMIO BAR detection (Thanks to Bob Picco)
 - Fix odd-sized transfers with a wide bus (Thanks to Larry Stephens)
 - Write posting fixes (Thanks to Thibaut Varene)
 - Change one of the GFP_KERNEL allocations back into a GFP_ATOMIC
 - Make CCB_BA() return a script-endian address
 - Move range checks and disabling of devices from the queuecommand path
   to slave_alloc()
 - Remove a warning in sym_setup_cdb()
 - Keep a pointer to the scsi_target instead of the scsi_dev in the tcb
 - Remove a check for the upper layers passing an oversized cmd
 - Replace CAM_REQ_ constants with the Linux DID_ constants
 - Replace CAM_DIR_ constants with the Linux DMA_ constants
 - Inline sym_read_parisc_pdc() on non-parisc systems
