x86/apic: Get rid of apic->target_cpus The target_cpus() callback of the apic struct is not really useful. Some APICs return cpu_online_mask and others cpus_all_mask. The latter is bogus as it does not take holes in the cpus_possible_mask into account. Replace it with cpus_online_mask which makes the most sense and remove the callback. The usage sites will be removed in a later step anyway, so get rid of it now to have incremental changes.

x86/platform: Move APIC ID validity check into platform APIC code Move APIC ID validity check into platform APIC code, so it can be overridden when needed. For NumaChip systems, always trust MADT, as it's constructed with high APIC IDs. Behaviour verifies on standard x86 systems and on NumaChip systems with this, and compile-tested with allyesconfig.
