DesignWare I2S controller

Required properties:
 - compatible : Must be "snps,designware-i2s"
 - reg : Must contain the I2S core's registers location and length
 - clocks : Pairs of phandle and specifier referencing the controller's
   clocks. The controller expects one clock: the clock used as the sampling
   rate reference clock sample.
 - clock-names : "i2sclk" for the sample rate reference clock.
 - dmas: Pairs of phandle and specifier for the DMA channels that are used by
   the core. The core expects one or two dma channels: one for transmit and
   one for receive.
 - dma-names : "tx" for the transmit channel, "rx" for the receive channel.
