reset: convert the core API to using firmware nodes

In order to simplify the commit converting the internals of reset core
to using firmware nodes, first convert the user-facing API. Modify the
signature of the core consumer functions but leave the specialized
wrappers as is to avoid modifying users for now.

No functional change intended.
