uio_pdrv_genirq: get irq through platform resource if not set otherwise 



Platform devices are configured through platform resources. The interrupt
in the driver uio_pdrv_genirq is instead configured through a side channel
i.e. the platform data structure. Make it possible to use the generic
configuration scheme via platform resource.
