[PATCH] dt-bindings: display: nxp, tda998x: Fix 'audio-ports' constraints

[Rob Herring]

The constraints for 'audio-ports' don't match the description. There can
be 1 or 2 DAI entries and each entry is exactly 2 values. Also, the
values' sizes are 32-bits, not 8-bits. Move the size constraints to the
outer dimension (number of DAIs) and add constraints on inner array
values.
