Christoph Hellwig 44a0337b32 powerpc/dma: split the two __dma_alloc_coherent implementations ...

The implemementation for the CONFIG_NOT_COHERENT_CACHE case doesn't share
any code with the one for systems with coherent caches.  Split it off
and merge it with the helpers in dma-noncoherent.c that have no other
callers.
