Yeah, I wanted to check where exactly did we mark the nodes online,
and for the few architectures I checked it happens in setup_arch(),
which is called very early in start_kernel(), while driver_init()
gets called through arch_call_rest_init(), which happens at the end
of the function.

I am not sure whether we want to remark that somehow in the changelog,
so it is crystal clear that by the time the node_dev_init() gets called,
we already set the nodes online.

Anyway, just saying, but is fine as is.
