sysfs: refactor findPhandleMatch
- Use same indenting style as the rest of the application.
- Invert branch logic to reduce indent levels.
- Move logic that does not depend on loop variants outside loop.
- Fix a bug where the io-channels phandle is read from the wrong file.
- Remove unnecessary try/catch block around DT IOs (DT is immutable).
- Export findPhandle so other modules can use it.
- Document current method limitations.
