You shouldn't need redistributor-stride here, unless your GIC
implementation is not compliant with the architecture (i.e. really
buggy). I only know of one such implementation, and I'd rather you
remove this property unless your GIC is indeed non-compliant. If that's
the case, you should also document it.
