ARM: shmobile: apmu: Move cpu_leave_lowpower() to SUSPEND section
cpu_leave_lowpower() is used for suspend only, not for CPU hotplug. Hence move it from the HOTPLUG_CPU || SUSPEND section to the SUSPEND section. Signed-off-by: Geert Uytterhoeven <geert+renesas@glider.be> Signed-off-by: Simon Horman <horms+renesas@verge.net.au>
