ARM: iop32x: offset IRQ numbers by 1



iop32x is one of the last platforms to use IRQ 0, and this has apparently
stopped working in a 2014 cleanup without anyone noticing. This interrupt
is used for the DMA engine, so most likely this has not actually worked
in the past 7 years, but it's also not essential for using this board.

I'm splitting out this change from my GENERIC_IRQ_MULTI_HANDLER
conversion so it can be backported if anyone cares.

Fixes: a71b092a ("ARM: Convert handle_IRQ to use __handle_domain_irq")
