[SCSI] Merge sym53c8xx_comm.h and sym53c8xx_defs.h into ncr driver

When the sym1 driver was in the tree, it used to share various parts of
its infrastructure with the ncr driver.  Now it's gone, these files are
just an annoyance, so merge sym53c8xx_comm.h into ncr53c8xx.c and merge
sym53c8xx_defs.h into ncr53c8xx.h.

-**
-**  Copyright (C) 1998-2001  Gerard Roudier <groudier@free.fr>

-**  revisions of 53C815 controllers.

-**  This driver is based on the Linux port of the FreeBSD ncr driver.

-**
-**          Gerard Roudier              <groudier@free.fr>
-**
-**  Being given that this driver originates from the FreeBSD version, and
-**  in order to keep synergy on both, any suggested enhancements and corrections
-**  received on Linux are automatically a potential candidate for the FreeBSD 
-**  version.
-**
-**  The original driver has been written for 386bsd and FreeBSD by
-**          Wolfgang Stanglmeier        <wolf@cologne.de>
