For all these APIs the rationale is very simple. If you have callback that
takes a pointer to the container (*), you better use the APIs related to
this container (no need to have an explicit dereferencing). Otherwise you
use dev_*() APIs (when it's pointer to the pure struct device).
The value is to have coherent APIs around struct device containers.
*) under container here I assume the data structure that has the embedded
struct device in it.
