[patch] More defines for dma-mapping-broken.h

[Heiko Carstens <heiko.carstens@de.ibm.com>]

From: Heiko Carstens <heiko.carstens@de.ibm.com>

9ac7849e35f705830f7b016ff272b0ff1f7ff759 causes this on s390.
Since we don't support DMA extend dma-mapping-broken.h a bit.

drivers/base/dma-mapping.c: In function `dmam_noncoherent_release':
drivers/base/dma-mapping.c:32:
	warning: implicit declaration of function `dma_free_noncoherent'
drivers/base/dma-mapping.c: In function `dmam_alloc_noncoherent':
drivers/base/dma-mapping.c:129:
	warning: implicit declaration of function `dma_alloc_noncoherent'
drivers/base/dma-mapping.c:129:
	warning: assignment makes pointer from integer without a cast
