soundwire: intel_ace2x: add empty new ops for LunarLake

Browse Source 
The register map and programming sequences for the ACE2.x IP are
completely different and need to be abstracted with a different set of
callbacks.

This initial patch adds a new file, follow-up patches will add each
required callback.
