Add support for sn201202x (a.k.a ACE3), an Apple-specific tps6598x variant that wraps the tps6598x core register set with a SPMI based regmap-like protocol, first appearing in Apple M3 devices. This series first makes the core parts bus-agnostic, and then adds the new SPMI interface as a custom regmap implementation. To simplify the merge strategy, the device tree entries will be sent in a future patch series.
