realtek: rtl838x: add gpio-ranges for pinctrl

For completeness, add the (known) GPIO pin mappings to the pinctrl node,
indicating the positions of these pins on the SoC package.

For 5.10 kernels, this results in a warning during boot:

    gpiochip_add_data_with_key: GPIOs 488..511 (18003500.gpio-controller) failed to register, -517

This warning is due to the GPIO driver returning -EPROBEDEFER, as the
pinctrl driver hasn't loaded yet. The driver will correctly load at some
later point, and the warning is quelled on later kernel versions.
