Subject: [PATCH v2 3/4] dt-bindings: remoteproc: qcom: wcnss: Add qcom,pronto compatible

The qcom,pronto compatible is used in the wcn36xx driver to determine
which register to access. However, this compatible was not documented.
This patch documents the existing compatible as is, since it isn't
immediately clear why the wcn36xx driver uses this extra compatible,
rather than relying directly on the regular compatible string.
