[PATCH] ASoC: dt-bindings: renesas, rsnd: Fix duplicate 'allOf' entries

[Rob Herring]

Commit e52f3f291152 ("ASoC: audio-graph-card: Refactor schema") added an
'allOf' entry, but one is already present in the schema. Multiple keys
is not valid and results in an error:

ruamel.yaml.constructor.DuplicateKeyError: while constructing a mapping
  in "<unicode string>", line 4, column 1
found duplicate key "allOf" with value "[]" (original value: "[]")
  in "<unicode string>", line 262, column 1

Fixes: e52f3f291152 ("ASoC: audio-graph-card: Refactor schema")
