[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 <[email protected]> Acked-by: Sam Ravnborg <[email protected]>
