[v2,1/5] Revert "soc: qcom: smd-rpm: Match rpmsg channel instead of compatible"

Commit Message

The rpm_requests device nodes have the compatible node. As such the
rpmsg core uses OF modalias instead of a native rpmsg modalias. Thus if
smd-rpm is built as a module, it doesn't get autoloaded for the device.
