gpio: rdc321x: Convert PCIBIOS_* return codes to errnos

Browse Source 
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.
