Justin T. Gibbs 1affda38c1 Add two new aic7xxx driver options:
AHC_FORCE_PIO - This forces the driver to use PIO even on systems that
	say they have memory mapped the controller's registers.  This
	seems to fix Ken Lam's problems.  I've also placed this option
	in the GENERIC kernel file so that we are guaranteed to install
	even on these flakey machines.

AHC_SHARE_SCBS - This option attempts to share the external SCB SRAM on
	the 398X controllers allowing a totoll of 255 non-paged SCBs.
	This doesn't work quite yet, so this option is mostly here to
	help 398X owners to experiment and give me feedback until this
	works properly.
