This function has a __weak definition and an override that is only used on
freescale powerpc chips. The powerpc definition however does not see the
declaration that is in a .c file:
arch/powerpc/kernel/dma-mask.c:7:6: error: no previous prototype for 'arch_dma_set_mask' [-Werror=missing-prototypes]
Move it into the linux/dma-map-ops.h header where the other arch_dma_* functions
are declared.

Instead of letting the architecture supply all of dma_set_mask just
give it an additional hook selected by Kconfig.
