ASoC: wm_hubs: Special case headphones for digital paths in more use cases
The optimisations which we can do with caching the headphone DCS result in wm_hubs have only been enabled in cases where class W is enabled. However, there are more use cases which can benefit from the cache, especially with WM8994 series devices with their more advanced digital routing. Rather than keying off the class W information from the CODECs have a check in wm_hubs for a suitable path and use that to determine if we can deploy our headphone optimisations.
