Khadas Edge2 uses the PCI-e Ampak AP6275P 2T2R Wi-Fi 6 module. The
pcie@0 node can be used as Bridge1, so the wifi@0 node is used as a
device under the Bridge1. As a PCIe device the wifi@0 can be probed
without compatible.

Where is the compatible (again!)? Test your code - you will see your
binding is a no-op.
