ARM/orion/gpio: Prepare gpio_irq_handler for irq argument removal 

The irq argument of most interrupt flow handlers is unused or merily
used instead of a local variable. The handlers which need the irq
argument can retrieve the irq number from the irq descriptor.

In this case the irq argument is shadowed by a local variable already,
so just rename it.

Search and update was done with coccinelle and the invaluable help of
Julia Lawall.
