[PATCH 1/2] driver core: Clear FWNODE_FLAG_NOT_DEVICE when a device is added

[Herve Codina]

Since commit 1a50d9403fb9 ("treewide: Fix probing of devices in DT
overlays"), when using device-tree overlays, the FWNODE_FLAG_NOT_DEVICE
is set on each overlay nodes.
When an overlay contains a node related to a bus (i2c for instance)
and its children nodes representing i2c devices, the flag is cleared for
the bus node by the OF notifier but the "standard" probe sequence takes
place (the same one is performed without an overlay) for the bus and
children devices are created simply by walking the children DT nodes
without clearing the FWNODE_FLAG_NOT_DEVICE flag for these devices.

Clear the FWNODE_FLAG_NOT_DEVICE when the device is added, no matter if
an overlay is used or not.
