Selecting CONFIG_MRAA_GPIO should automatically select GPIO driver

It would seem that it's done already these days in https://github.com/intel-iot-devkit/zmraa/blob/master/Kconfig#L33. Or you mean some specific driver?

I would prefer leaving the choice of the specific driver with the user (for now), because Zephyr supports a lot of boards and then some of the boards have multiple choices. We could eventually have a macro in place which helps choose the best driver for a particular board at compile time or something like that.

Can we close this?
