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

[Bartosz Golaszewski]

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. Set it as
the secondary firmware node of the platform device to enable proper
fwnode-based GPIO lookup.
