Subject: [PATCH v3 2/2] arm64: dts: exynos: Move syscon poweroff and restart nodes under the PMU

The PMU node is the actual block responsible for power management,
including typical Exynos on/off/restart procedures.  Therefore the
syscon poweroff and restart nodes logically belong to it.

Signed-off-by: Krzysztof Kozlowski <krzk@...nel.org>

Previously was "Fix missing missing reg warning for syscon restart
nodes" to fix DTC warnings like:

    arch/arm64/boot/dts/exynos/exynos7-espresso.dtb: Warning (simple_bus_reg):
        Node /soc/syscon-reboot missing or empty reg/ranges property

but this warnings are gone in v4.17-rc1 since 9130ba884640
("scripts/dtc: Update to upstream version v1.4.6-9-gaadd0b65c987")
