The driver overrides the error code returned by platform_get_irq() to

I wouldn't usually expect an SMMU to be wired up to a secondary
interrupt controller that could cause deferral, but on the other hand I
don't think there's any good reason *not* to propagate the original
error anyway, so sure, why not.
