It's probably a net detriment to use a template in this scenario.

Breaks Chipset::perform into read and write.
This allows each to call the other when a read occurs of a write-only address, and vice versa.

Clarifies wait-for-CPU-slot semantics.
Big bonus: this guarantees `advance_dma`s will be called at most once per output cycle, even if they return `false`.
