m32r: use generic sys_pipe
m32r can use the generic sys_pipe implementation. The current sys_pipe implementation on m32r only differes from the generic one by passing a lot of additional unused registers to sys_pipe. Reviewed and tested by Hirokazu Takata. Signed-off-by: Christoph Hellwig <hch@lst.de> Acked-by: Hirokazu Takata <takata@linux-m32r.org> Signed-off-by: Linus Torvalds <torvalds@linux-foundation.org>
