irqchip/gic: Make quirks matching conditional on init return value
As it turns out, the IIDR is not sufficient to distinguish between GICv3 implementations when it comes to enabling quirks. So update the prototype of the init() hook to return a bool, and interpret a 'false' return value as no match, in which case the 'enabling workaround' log message should not be printed.
