EDAC/altera: Use parent device for devres in altr_portb_setup()

Browse Source 
Anchor the devres group and the devm-managed IRQ requests in altr_portb_setup()
to the actual parent device (device->edac->dev) instead of the embedded struct
device inside the copied per-port altr_edac_device_dev.

This keeps devres_open_group(), devm_request_irq(), devres_remove_group() and
devres_release_group() all referring to the same long-lived device so the
group and the resources allocated inside it are torn down together.
