Move existing numa global numa_info (renamed as "nodes") into NumaState.

Suggested-by: Igor Mammedov <imammedo@redhat.com>
Suggested-by: Eduardo Habkost <ehabkost@redhat.com>
Signed-off-by: Tao Xu <tao3.xu@intel.com>

No changes in v7.

Changes in v6:
    - Rebase to upstream, move globals in arm/sbsa-ref
    - Correct some mistake(Igor)
    - Use ms->numa_state->nodes directly, when use it once or twice(Igor)
