Subject: [PATCH 2/6] dt-bindings: misc: google,android-pipe: Convert to DT schema

Convert the Android Goldfish QEMU Pipe binding to DT schema format.
Move the file to the misc directory as it represents a miscellaneous
communication device.
Update the example node name to 'pipe' to comply with generic node
naming standards and fix the mismatch between unit address and reg
property in the original example.
