ARM: pxa: pxa27x: attach software node to its target GPIO controller

Software node describing the GPIO controller for the pxa27x platforms is
currently "dangling" - it's not actually attached to the relevant
controller and doesn't allow real fwnode lookup. Attach it once it's
registered as a firmware node before adding the platform device.
