Convert the AK4458 audio DAC bindings to DT schema.
Signed-off-by: Saalim Quadri <[email protected]>
---
Changes:
V1 -> V2: Use the correct way for dsd-path property
Drop ak4458 label form example
V2 -> V3: ak4458 is the only one that does not support dsd-path, so we
do not require to define an array

What happened to dsd-path? Do not remove properties from the bindings
without some valid reason.
