ASoC: SOF: debug: show firmware/topology prefix/names
The SOF driver has multiple profiles to select firmware/topology prefix/names depending on the platform and ipc_type, and each of those fields can be overridden with kernel parameters. This results in some cases in confusion on what configuration is actually used in a given test. We currently log the firmware and topology names in the kernel logs, but there's been an ask to add the information in debugfs to simplify test scripts used by developers and CI. This isn't meant to be a stable ABI used by apps, changes will be allowed as needed.
