ASoC: davinci-mcbsp: add binding for McBSP
Add devicetree binding for the TI DA850/OMAP-L138/AM18xx MultiChannel Buffered Serial Port (McBSP) The optional register range "dat" is not implemented at the moment. The current driver supports only DMA into RX/TX registers but no FIFO. Once the FIFO is implemented in the driver the "dat" range will be used.
