ASoC: dt-bindings: adi,adau17x1: Convert to DT schema

Convert the binding document for adi,adau17x1 from txt to yaml so one could validate dt-entries correctly and any future additions can go into yaml format. Add address and size cells to example to prevent errors regarding reg format.

---
Changes since v1:
- added 'Codec' in title to clarify type of devices
- put compatible devices in lexographic order
- changed description of clocks
- changed 'unevaluatedProperties' to 'additionalProperties'
- changed node names to be generic

-			"adi,adau1961"
-			"adi,adau1381"

Why this is still RFC? RFC means it is not ready for applying, not full review, just some glance and comments. Some maintainers will not apply RFC patches at all. What do you question here?
