realtek: wire up GPIO fan for Zyxel XS1930 switches

Browse Source 
The switches from Zyxels XS1930 have one or two fans in the case. They
might be controlled in a limited fashion. There's a single GPIO which -
depending on the state - drives the fan in slow or fast mode. Wire that
up as a device tree node to be able to control that in userspace.

XS1930-10 and XS1930-12HP use the same GPIO while XS1930-12F moves that
to one of its GPIO expanders. Also add 'kmod-hwmon-gpiofan' for all
three devices to be selected by default.
