[SCSI] sym53c8xx: Remove pci_dev pointer from sym_shcb

This structure is accessed by the device; the fewer Linux things in it,
the better.  Using the pci_dev pointer from the hostdata requires a lot
of changes:

 - Pass Scsi_Host to a lot of routines which currently take a sym_hcb.
 - Set the Scsi_Host as the pci drvdata (instead of the sym_hcb)
