fix ATH_SPECTRAL dependency

As ATH_SPECTRAL is an option of ATH_DEBUG, ATH_DEBUG must be also selected. If it is not selected then ATH_SPECTRAL is also not selected (this may be a bug or known limitation of the config system).

Also fix the name of the dependency, it doesn't have to start with CONFIG.
