Subject: [PATCH] asoc/multi-component: fsl: add support for 36-bit physical
 addresses

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.
