macaudio: Disable j313 and j274

We are going to enable these out of band. If you are a distro packager:

** WARNING: **
** YOU ABSOLUTELY NEED THIS PATCH IN YOUR LSP-PLUGINS PACKAGE **

lsp-plugins/lsp-dsp-lib#20

Do NOT enable speakers without that patch, on any model. It can/will
result in nasty noise that could damage them.
