rdc_gpio_config() uses pci_{read,write}_config_dword() that return PCIBIOS_* codes. rdc_gpio_config() is used for direction_{input,output}() in the struct gpio_chip which both require normal errnos to be returned. Similarly, rdc321x_gpio_probe() that is probe function returns PCIBIOS_* codes without converting them first into normal errnos. Convert PCIBIOS_* returns code using pcibios_err_to_errno() into normal errno before returning them to fix both issues.
