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.
