    ARM: dma-mapping: remove custom consistent dma region

arch/arm/mm/dma-mapping.c:575: error: macro "__alloc_from_pool" requires 4 arguments, but only 2 given
arch/arm/mm/dma-mapping.c:575: error: '__alloc_from_pool' undeclared (first use in this function)

make[1]: *** [arch/arm/mm/dma-mapping.o] Error 2
