powerpc: Implement dma_mmap_coherent()
This is used by Alsa to mmap buffers allocated with dma_alloc_coherent() into userspace. We need a special variant to handle machines with non-coherent DMAs as those buffers have "special" virt addresses and require non-cachable mappings Signed-off-by: Benjamin Herrenschmidt <benh@kernel.crashing.org>
