Subject: [PATCH v4 0/9] More Rust bindings for device property reads

changes in v4:
* Avoid code duplication in `FwNode::display_path`.
* Add missing safety comment.
* Replace `PropertyGuard::required` with `PropertyGuard::required_by`
  to associate logs with the proper device.
* Split commit moving property_present into three separate ones:
  1. Create FwNode abstraction.
  2. Access FwNode via Device.
  3. Move property_present from Device to FwNode.

Best regards,
Remo
