While e3a3c3a20555 ("UIO: fix uio_pdrv_genirq with device tree but no
interrupt") added support for using uio_pdrv_genirq for devices without
interrupt for device tree platforms, the removal of uio_pdrv in
26dac3c49d56 ("uio: Remove uio_pdrv and use uio_pdrv_genirq instead")
broke the support for non device tree platforms.
This change fixes this, so that uio_pdrv_genirq can be used without
interrupt on all platforms.
This still leaves the support that uio_pdrv had for custom interrupt
handler lacking, as uio_pdrv_genirq does not handle it (yet).
Fixes: 26dac3c49d56 ("uio: Remove uio_pdrv and use uio_pdrv_genirq instead")
