driver core: change to_subsys_private() to use container_of_const()
The macro to_subsys_private() needs to switch to using
container_of_const() as it turned out to being incorrectly casting a
const pointer to a non-const one. Make this change and fix up the one
offending user to be correctly handling a const pointer properly.
