This is a new attempt to add it back with much less potential build problems. For that I first simplify the existing qcom_scm_set_cold/warm_boot_addr() implementations. The idea is that cpu_logical_map(), MPIDR_AFFINITY_LEVEL() etc are not needed if we just set the entry address for all CPUs. Nothing in the mainline tree actually requires setting a different entry address for one particular CPU and I cannot really think of a use case for this.
