ASoC: dt-bindings: rt5682s: correct several errors

Correct several errors in rt5682s dtschema:
1. The examples should be under "examples":
    'example' is not one of ['$id', '$schema', 'title', 'description', 'examples', ...

2. Missing type for vendor properties

3. clock-names should be an array:
    properties:clock-names:items: {'const': 'mclk'} is not of type 'array'

4. Example DTS should include headers:
    [scripts/Makefile.lib:386: Documentation/devicetree/bindings/sound/realtek,rt5682s.example.dt.yaml] Error 1

5. Node name in example DTS misses unit address and does not match DT
   convention (generic name):
    Warning (reg_format): /example-0/rt5682s:reg: property has invalid length (4 bytes) (#address-cells == 1, #size-cells == 1)

6. Node address should be in size-cells:0 block in example DTS:
    Warning (reg_format): /example-0/codec@1a:reg: property has invalid length (4 bytes) (#address-cells == 1, #size-cells == 1)
