You are only adding RX0, what happens to RX1.. RX7

TBH, skipping other entries for ex CDC_DMA_RX will end up with sparse 
numbering.

Please add all the entries for CDC_DMA_RX and other ports as well.

Like:

#define LPASS_CDC_DMA_RX0	6
#define LPASS_CDC_DMA_RX1	7
#define LPASS_CDC_DMA_RX2	8
#define LPASS_CDC_DMA_RX3	9
#define LPASS_CDC_DMA_RX4	10
#define LPASS_CDC_DMA_RX5	11
#define LPASS_CDC_DMA_RX6	12
#define LPASS_CDC_DMA_RX7	13

You mean VA_TX0?

We really do not need this in bindings.
You could add this is some of the driver header files instead.
