powerpc: add SSI-to-DMA properties to Freescale MPC8610 HPCD device tree
Add the fsl,playback-dma and fsl,capture-dma properties to the Freescale MPC8610 HPCD device tree. These properties connect the SSI nodes to the DMA nodes for the DMA channels that the SSI should use. Also update the ssi.txt documentation. These properties will be needed when the ASoC V2 version of the Freescale MPC8610 device drivers are merged into the mainline.
