Useful for tick-only drivers like Pulpino that don't support this. Ideally we'd have a header-level interface definition for individual timer drivers to eliminate the noop function call, but this is clean for now (even the Pulpino hardware looks like it should support timeouts just fine, so effort would be better spent there than on a clean "ticked" interface).
