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.

What is the point of backporting this patch? It's only use is to enable a workaround that is not a pre-4.15 candidate.
Same for its equivalent in the 4.9 tree.
I missed that this is to support new hardware and that no such hardware exists before 4.15. I'll drop it, thanks!
