[Linux-stm32] [PATCH] dt-bindings: pinctrl: stm32: Fix 'st, syscfg' schema

[Rob Herring]

The proper way to add additional contraints to an existing json-schema
is using 'allOf' to reference the base schema. Using just '$ref' doesn't
work. Fix this for the 'st,syscfg' property.

I've got some other fixes queued up and can take this via the DT tree.
