Current x86 Device Tree implementation does not support multiprocessing.
Add new "intel,apic-id" property to allow using CPU descriptions
in Device Tree data provided by the U-Boot loader.
Address specified in 'reg' to be used as default local APIC ID
to avoid breaking existing systems with DTB provided by firmware.
