[PATCH 41/41] ARM: dts: r8a7792: add SMP support

From: Sergei Shtylyov <sergei.shtylyov at cogentembedded.com>

Add the device tree nodes for the Advanced Power Management Unit (APMU)
and the second Cortex-A15 CPU core.
Use the "enable-method" prop  to point out that the APMU should be used
for the SMP support.
