From: Pierre-Louis Bossart <pierre-louis.bossart@xxxxxxxxxxxxxxx>
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.
