sparc: Pull the unimplemented formats out of the ISA description.
These are simple classes which don't need to be in the ISA description. Change-Id: Ia0bb45f50c4da2536855efcb3c17c7780b431332 Reviewed-on: https://gem5-review.googlesource.com/5464 Reviewed-by: Gabe Black <gabeblack@google.com> Maintainer: Gabe Black <gabeblack@google.com>
