[PATCH v2 1/2] dt-bindings: soc: samsung: exynos-pmu: remove syscon for google,gs101-pmu

[Peter Griffin <peter.griffin@linaro.org>]

Since commit ba5095ebbc7a ("mfd: syscon: Allow syscon nodes without a
"syscon" compatible") it is possible to register a regmap without the
syscon compatible in the node.

Update the bindings for google,gs101-pmu so that the syscon compatible is
no longer required. As it isn't really correct to claim we are compatible
with syscon (as a mmio regmap created by syscon will not work on gs101).

Additionally (with the benefit of hindsight) PMU register writes were never
working with a MMIO syscon on gs101, so the ABI break is justified.
