While trying to work on adding audiodump support for CLI, I was alerted that it was important to first try moving the DSP configs to the new config before continuing, as that makes it substantially easier to write clean code to add such a feature. This commit aims to allow for Dolphin to only rely on the new config for DSP-related settings.
