platform/x86: barco-p50-gpio: attach software node to its target GPIO device

The software node representing the GPIO controller to consumers is
"dangling": it's not really attached to the device. The GPIO lookup
relies on matching the name of the node to the chip's label. Switch to
using platform_device_register_full() and use the swnode field of struct
platform_device_info to attach the software node to the GPIO device.
