- In stm32_exti_alloc function, discards irq_domain_set_info
  with handle_simple_irq. This overwrite the setting defined while init
  of generic chips. Exti controller manages edge irq type.
- Removes acking in chained irq handler as this is done by
  irq_chip itself inside handle_edge_irq
- removes unneeded irq_domain_ops.xlate callback

Nit: the "From:" should match the SoB line (the address does, but not
the name). I can fix that up when I apply the series.

Thanks,
