[PATCH v4 4/5] arm64: dts: exynos: gs101: add pmu-intr-gen syscon node

[Peter Griffin]

Add syscon node for the PMU Interrupt Generation registers.

Additionally update the exynos-pmu node to provide a phandle
to pmu-intr-gen syscon.

These registers are required for CPU hotplug to be functional.

Changes since v1:
* Model pmu-intr-gen as it's own syscon (Krzysztof)
