There are 4 TDM controllers on the SoC. Each controller can receive or
transmit data over DMA. The dma it self has 8 channels.
Each channel can be connected only to a specific i2s node. But each
of dma channel can have multiple purposes so in order to save dma
channels the configurations allows to use tx and rx, only rx, only tx
or none channels. I2S controller without channels can be useful in
configuration where I2S is used as clock source only and doesn't
produce any data.
