The QFN20 part has a different GPIO/port function assignment. The configuration struct bit field ordered as TX/RX/RS485/WAKEUP/CLK which exactly matches GPIO0-3 for QFN24/28. However, QFN20 has a different GPIO to primary function assignment. Special case QFN20 to follow to properly detect which GPIOs are available.
