[PATCH] s390: Use include/asm-generic/dma-mapping-broken.h

ChangeSet 1.1371.413.23 [1] introduced the file
include/asm-generic/dma-mapping-broken.h for architectures that don't
support the new DMA API. I don't know if this is the case with s390,
however, ChangeSet 1.1371.445.6 [2] introduced a set of changes that
duplicate those in include/asm-generic/dma-mapping-broken.h.

This patch squishes that duplication by simply including
include/asm-generic/dma-mapping-broken.h in
include/asm-s390/dma-mapping.h.
