Better to be the values with AC_WCAP_*.

Avoid unnecessary changes like this.

So this is about the generic ID (with Realtek vendor-id).
It's most likely OK, as such an ID is used only for some reference
board or such, but it should be mentioned in the changelog.

Ditto, better to mention the available model name in the changelog,
too.

Once after all those are fixed / improved, please resubmit the patch.
