percpu: move pcpu_lpage_build_unit_map() and pcpul_lpage_dump_cfg() upward
Unit map handling will be generalized and extended and used for embedding sparse first chunk and other purposes. Relocate two unit_map related functions upward in preparation. This patch just moves the code without any actual change. Signed-off-by: Tejun Heo <tj@kernel.org>
