feat(per-cpu) : change highlights
* introduce per-cpu framework with/without NUMA support
* introduce base layer for faster assembly access
* platforms to port numa related platform APIs if NUMA awareness is
enabled.
* plat_per_cpu_section_base
* plat_zero_init_per_cpu_section
Please note that changes to hand-off NUMA nodes and corresponding CPU
mappings is not part of the branch. There is plan to scope and see if
this could be added as a feature down the line. It is likely that the
platform port would change shape with the hand-off coming in.
