The acornscsi driver was added in v2.1.88. It has always #undef-ed
CONFIG_SCSI_ACORNSCSI_LINK near the top of acornscsi.c. And, just to be
sure, it has also always triggered a preprocessor error if
CONFIG_SCSI_ACORNSCSI_LINK was still defined. But, as far as I can see,
it has never even been possible to set SCSI_ACORNSCSI_LINK through
kconfig, or its predecessors, in the first place.
Let's remove the code involved.

Untested.
Also interesting: SCSI_ACORNSCSI_TAGGED_QUEUE can be set through
kconfig, but its macro will be #undef-ed at the top of acornscsi.c. I
suppose that #undef could be dropped.
And finally: CONFIG_ACORNSCSI_CONSTANTS has to be set manually. But if
we'd just drop the CONFIG_ prefix acornscsi.c would become a pet peeve
free zone.
