WCD9385 audio codec TX port mapping was copied form HDK8450, but in fact
it is offset by one.  Correct it to fix recording via analogue
microphones.

The change is based on QRD8550 and should be correct here as well, but
was not tested on MTP8550.

Would this not be codec-and-not-board-specific, anyway?

Yes, indeed, it should be.

Should we move this to the driver and drop the then-uselesss
dt property?

Actually it's codec-and-soc specific, so I'm against dropping this.

On the sc8280xp & sc7280 it requires a different mapping because the
TX macro changed the way to map the soundwire channels since (at least) SM8450.
