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

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).
