realtek: gpio: backport rtl9607c gpio support patches

This commit backports 2 patches that add gpio controller support
to RTL9607C SoCs. It enables us to make use of anything that
can be controlled by GPIO on RTL9607C, like LEDs, buttons and such.

+
+The RTL9607C SoC has support for 3 GPIO banks with 32 GPIOs each and
+the port order is reversed just like in RTL930x.
