arm64: dts: exynos8895: Add m2-pmu, poweroff and reboot

Hey folks,

This series adds support for the mongoose cluster PMU in DT hence
a compatible for that was recently added.

After this patchset, I'm planning to submit patches for more hardware
support.

Kind regards,
Ivo.

Changes since v2:
 - Dropped the poweroff and reboot patch, since it works as-is with the
   included dtsi.

Since we have a PMU compatible for Samsung's Mongoose cores now, drop
the comment that explains the lack of it and define the node.
