The HSP does not exist on any chip prior to Tegra186, which is what the
dependency reflects. However, I agree that there is little point for an
exact list of per-chip dependencies. We don't really support non-multi-
platform kernels anymore, or at least they don't get any testing, so
relaxing the dependency is fine with me.
