Subject: [PATCH 10/9] dt: deps: fix bug not registering late drivers when OF_DEPENDENCIES is disabled

The subject says all. Patch 5/9 has a bug which avoids registering late drivers
if OF_DEPENDENCIES is disabled.

This also explains the large differences in boot times I've experienced when
comparing boot times with and without DT dependency based initialization order.
