[CRIS] Merge asm-offsets.c for both arches into one file.
Eliminates the link to arch specific asm-offsets.c from CRIS architecture build system. Resulting asm-offsets.s are identical before and after change for both arch-v10 and arch-v32. Signed-off-by: Jesper Nilsson <jesper.nilsson@axis.com> Acked-by: Sam Ravnborg <sam@ravnborg.org>
