ARMv8: get new GD address from gd->new_gd directly
the new GD address is calculated via board data BD currently
it require the new GD area locates below BD tightly, so a strict
constraint is imposed on memory layout which maybe make special
platform unpleasant.
fix it by getting new GD address from gd->new_gd directly.
