on x86 currently range 0..max_cpus is used to generate architecture-dependent CPU ID (APIC Id) for each present and possible CPUs. However architecture-dependent CPU IDs list could be sparse and code that needs to enumerate all IDs (ACPI) ended up doing guess work enumerating all possible and impossible IDs up to apic_id_limit = x86_cpu_apic_id_from_index(max_cpus). That leads to creation of MADT entries and Processor objects in ACPI tables for not possible CPUs. Fix it by allowing board specify a concrete list of CPU IDs accourding its own rules (which for x86 depends on topology). So that code that needs this list could request it from board instead of trying to guess what IDs are correct on its own. This interface will also allow to help making AML part of CPU hotplug target independent so it could be reused for ARM target.
