[PATCH v4] ARM: dts: r8a7794: Add SMP support

[geert+renesas@glider.be (Geert Uytterhoeven)]

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

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
for the SMP support.
