Update the fsl-ssi bindings. DMA is no required property anymore and uses the generic DMA bindings. imx-fiq is a new alternative to DMA

Notes: Changes in v3: - In previous versions, I removed fsl,playback-dma and capture-dma. But they are still in use by fsl_dma.c, so I added them again.

+Note that either dmas, dma-names or fsl,imx-fiq are required. + Optional properties: - codec-handle: Phandle to a 'codec' node that defines an audio codec connected to this SSI.
