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.
