gpio-f7188x: Add GPIO support for Nuvoton NCT6116

Browse source

Add GPIO support for Nuvoton NCT6116 chip. Nuvoton SuperIO chips are
very similar to the ones from Fintek. In other subsystems they also
share drivers and are called a family of drivers.

For the GPIO subsystem the only difference is that the direction bit is
reversed and that there is only one data bit per pin. On the SuperIO
level the logical device is another one.

On a chip level we do not have a manufacturer ID to check and also no
revision.
