Right now MST audio is causing too many kernel panics to really keep around in the kernel. On top of that, even after fixing said panics it's still basically non-functional (at least on all the setups I've tested it on). Revert until we have a proper solution for this.
This reverts commit 3d52ccf52f2c51f613e42e65be0f06e4e6788093.

Applied (with appropriate Fixes: and cc: stable tags), thanks. -Daniel
