driver core: remove polling for driver_probe_done(v5)
This patch removes 100ms polling for driver_probe_done in wait_for_device_probe(), and uses wait_event() instead. Removing polling in fs initialization may lead to a faster boot. This patch also changes the return type of wait_for_device_done() from int to void. This patch is against Arjan's patch in linux-next tree.
