Marius Strobl d7405474ea - Const'ify firmware and lookup-tables. 
- Obsolete redundant inst_name and unit members of struct sym_hcb.
- Fix three more NULL vs. 0 confusions.
- Use device_set_softc(9) to tell the bus layer that this driver
  allocates a instance of struct sym_hcb itself.

/*-
* Device driver optimized for the Symbios/LSI 53C896/53C895A/53C1010
* PCI-SCSI controllers.
*
* Copyright (C) 1999-2001 Gerard Roudier <groudier@free.fr>
*
* This driver also supports the following Symbios/LSI PCI-SCSI chips:
* 53C810A, 53C825A, 53C860, 53C875, 53C876, 53C885, 53C895,
* 53C810, 53C815, 53C825 and the 53C1510D is 53C8XX mode.
*
*
* This driver for FreeBSD-CAM is derived from the Linux sym53c8xx driver.
* Copyright (C) 1998-1999 Gerard Roudier
*
* The sym53c8xx driver is derived from the ncr53c8xx driver that had been
* a port of the FreeBSD ncr driver to Linux-1.2.13.
*
* The original ncr driver has been written for 386bsd and FreeBSD by
* Wolfgang Stanglmeier <wolf@cologne.de>
* Stefan Esser <se@mi.Uni-Koeln.de>
* Copyright (C) 1994 Wolfgang Stanglmeier
*
* The initialisation code, and part of the code that addresses
* FreeBSD-CAM services is based on the aic7xxx driver for FreeBSD-CAM
* written by Justin T. Gibbs.
*
* Other major contributions:
*
* NVRAM detection and reading.
