Add the device tree node for the Advanced Power Management Unit (APMU).
Use the "enable-method" prop to point out that the APMU should be used

This patch is against the 'renesas-devel-20160621-v4.7-rc4' tag of Simon
Horman's 'renesas.git' repo. It depends on Magnus'/Geert's SMP patchset...
SMP/PM basically works but you can't offline CPU0 (system hangs)...
