'sound-dai' is a common property, but has duplicate type definitions.
Create a new common definition to define the type and then update all
the other occurrences to just define how many entries there are just
like other phandle+arg properties.

The constraints on the number of entries is based on the examples and
could be wrong.

No min or max here. Links may have more than one codec.

What do you mean? Every 'sound-dai' there only has 1 phande+args. Each
codec is a child node.

Yes it is a child - sorry I misunderstood.
I thought the MaxItems: 1 would limit the number of codecs
