Virtual GPIOs do not have any hardware state associated with them. Any attempt to read back hardware state for these pins result in error codes. Skip dumping extra pin config information for these virtual GPIOs. Fixes: 184d8e13f9b1 ("pinctrl: mediatek: Add support for pin configuration dump via debugfs.")
