ARM: iop32x: offset IRQ numbers by 1
commit 9d67412f24cc3a2c05f35f7c856addb07a2960ce upstream.
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: a71b092a9c68 ("ARM: Convert handle_IRQ to use __handle_domain_irq")
