Hannes Reinecke 2dd951ecd5 scsi: Conditionally compile in constants.c
Instead of having constants.c littered with ifdef statements we should
be moving dummy functions into the header and condintionally compile in
constants.c if selected. And update the Kconfig description to reflect
the actual size difference.
