I'm not sure if your requirement is to create another dai-link. But
have you tried to simply add a new device node for the new dai-link?

Supposing two WM8962 chips on one board, there should be two WM8962
nodes hanging to the I2C node with different I2C slave addresses.

So you may need two different dai-link nodes for each of the WM8962
i2c nodes as well. And, of course, you need to specify different SSIs
and different AUDMUX ports for two dai-link nodes.

Then you will get two sound card in the system.
