At present we misuse print_cpuinfo() do so CPU init on x86. This is done because it is the next available call after the console is enabled. But several arches use checkcpu() instead. Despite the horrible name (which we can fix), it seems a better choice. Adjust the various x86 CPU implementations to move their init code into checkcpu() and use print_cpuinfo() only for printing CPU info.
