GICR for multiple CPU can be described with start address and stride,
or with multiple address. Current multiple address and stride are
both used. Fix it.

I've applied this one to fixes now.

Hi Olof,

I happened to still have this one in my todo folder as I must have
missed your reply, and I stumbled over it while looking for things
that may have gone missing.

I don't see it in v4.9-rc6, did it get dropped accidentally?
