I've retested with 5.7-rc2 (previous testing was on 5.6-rc# + the
"ASoC: SOF: Intel: hda-loader: clear the IPC ack bit after FW_PURGE" patch)
and I'm no longer seeing this. So I guess fixing this also needed some other
patches which have now landed in 5.7.

So this is resolved now and my patch for this can be dropped.
