[PATCH 2/3] driver core: provide new device flag - DEV_FLAG_SWNODE_NOTIFIER

[Bartosz Golaszewski <bartosz.golaszewski@oss.qualcomm.com>]

Extend the set of device flags with one that indicates to driver core
that this device was passed as argument to software_node_notify() and
took a reference to this device's software node.
