Saravana Kannan 81e7c6befa of: dynamic: Fix overlayed devices not probing because of fw_devlink
When an overlay is applied, if the target device has already probed
successfully and bound to a device, then some of the fw_devlink logic
that ran when the device was probed needs to be rerun. This allows newly
created dangling consumers of the overlayed device tree nodes to be
moved to become consumers of the target device.

[Herve: Add the call to driver_deferred_probe_trigger()]
[Herve: Use fwnode_test_flag() to test fwnode flags value]

Fixes: 1a50d9403f ("treewide: Fix probing of devices in DT overlays")
