driver core: make software nodes available earlier
Software nodes are currently initialized in a function registered as
a postcore_initcall(). However, some devices may want to register
software nodes earlier than that (or also in a postcore_initcall() where
they're at the mercy of the link order). Move the initialization to
driver_init() making swnode available much earlier as well as making
their initialization time deterministic.
