So I compiled the latest sof firmware from main branch commit
90c14e56cb, and now it seems I get additional errors that I didn't get a
few months ago when I last tried:

The kernel I'm running on is based on the asoc tree from Mark Brown:

Let me know what other information you need in order to debug this.
