bbu: Expose bbu_find_handler_by_*() functions

Expose bbu_find_handler_by_device() and bbu_find_handler_by_name() as
public functions and convert the only user of
barebox_update_handler_exists() to use the former function instead.

With this done, barebox_update_handler_exists() is no longer used
anywhere in the code and can be removed.
