Update the DMA driver used by the Freescale MPC8610 HPCD audio driver to support 36-bit physical addresses, for both DMA buffers and the SSI registers. The DMA driver calls snd_dma_alloc_pages() to allocate the DMA buffers for playback and capture. This function is just a front-end for dma_alloc_coherent(). Currently, dma_alloc_coherent() only allocates buffers in low memory (it ignores GFP_HIGHMEM), so we never actually get a DMA buffer with a real 36-bit physical address.
