I went on my first 'git bisect' action on the upstream code and that identified
commit 907f0a3051869a61499905377212500155bd28ec as the first bad commit, with
commit message "ASoC: simple-card: Fill in driver name".
No idea why that commit would break multichannel audio, but I built a 5.14.10
upstream kernel with 2 changes:
- Kernel config changes (to arm64/defconfig) ~ the same as I had proposed for
the Debian kernel (PMIC + audio related)
- Reverting of commit 907f0a3051869a61499905377212500155bd28ec
And when I booted into that, I had my multichannel audio back again \o/
I haven't yet built a new Debian kernel with this change, but I would be
extremely surprised if it wouldn't fix the issue there too.
FWIW, my 'git bisect' log:

I guess this should be reported upstream, but I have no idea who that would be
and how and where to report it.
