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)

Make sym_interrupt return an irqreturn_t instead of void, and take a
Scsi_Host instead of a sym_hcb.  Pass the Scsi_Host to the interrupt
handler instead of the sym_hcb.  Rename the host_data to sym_data.
Keep a pci_dev pointer in the sym_data.  Rename the Scsi_Host from
instance to shost.

By introducing the use_dac(), set_dac() and DMA_DAC_MASK macros, we can
eliminate a lot of ifdefs from the code.  We now rely on the compiler to
optimise away a few things that we'd formerly relied on the preprocessor
to do.  This makes sym_setup_bus_dma_mask() small enough to inline into
its only caller.

Instead of telling the reset routine that the command completed from
sym_eh_done, do it from sym_xpt_done.  The 'to_do' element of the ucmd
is redundant -- it serves only to tell whether eh_done is valid or not,
and we can tell this by checking to see if it's NULL.
