ARM/sa1111: Prepare sa1111_irq_handler for irq argument removal 

Author: Thomas Gleixner <tglx@linutronix.de>

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.

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