Subject: [PATCH 4/4] dt-bindings: mfd: syscon: require specific compatible also for simple-mfd

The syscon bindings require a device specific compatible, beside the
"syscon".  However schema counts "simple-mfd" as such, which allows
simple-mfd+syscon to sneak in.

Adjust the match to be sure simple-mfd also comes with a device specific
compatible.
