Remove all legacy function from system manager

This commit removes all of the un-used interfaces in
order to get it down to its bare function and to
make eventual removal of this legacy application
easier

Tested: Built image and verified witherspoon system
still powers on as expected and no new errors or issues
show up in basic regression.
