There was an off-list discussion, not sure if it reached you in the
end, but this won't fly. I was told there are at least two separate
core types (discernable by a different MIDR_EL1[PART_NUM] [1]), all
of which should have their own compatible, otherwise we will introduce
something as meaningless as qcom,kryo before - we want more
granularity, like arm,cortex-x1 or arm,cortex-a78 are separate.
