Add DT node for the Advanced Power Management Unit (APMU), add the
second CPU core, and use "renesas,apmu" as "enable-method".

Dear All,

I am reposting this patch now that its dependecy ("ARM: shmobile: rcar-gen2:
Make sure CNTVOFF is initialized on CA7/15") is part of v4.15-rc1, similarly
to patch "ARM: dts: r8a7794: Add SMP support".

v2:
- rebased against renesas-devel-20171205-v4.15-rc2

Thanks
