 * SDW0 Manager instance registers  6 CPU DAI (3 TX & 3 RX Ports)

 *     SDW0 Pin1 -> Port number 1 -> AUDIO1 TX
 *     SDW0 Pin2 -> Port number 2 -> AUDIO2 TX
 *     SDW0 Pin3 -> port number 3 -> AUDIO0 RX

 *  SDW1 Pin0 -> port number 0 -> AUDIO1 TX
 *  SDW1 Pin1 -> Port number 1 -> AUDIO1 RX
 *  Same mapping should be used for programming DMA controller registers in SoundWire DMA driver.
 * i.e if AUDIO0 TX channel is selected then we need to use AUDIO0 TX registers for DMA programming
