[PATCH -mm] fix for crash in adummy_init()

This was reported by Ingo Molnar here,

The problem is that adummy_init() depends on atm_init() , but adummy_init() is
called first.

So I put atm_init() into subsys_initcall which seems appropriate, and it will
still get module_init() if it becomes a module.

Interesting to note that you could crash your system here if you just load the
modules in the wrong order.
