reset: amlogic: aux: drop aux registration helper

Having the aux registration helper along with the registered driver is not
great dependency wise. It does not allow the registering driver to be
properly decoupled from the registered auxiliary driver.

Drop the registration helper from the amlogic auxiliary reset driver.
This will be handled in the registering clock driver to start with while
a more generic solution is worked on.
