[PATCH] dt-bindings: i2c: stm32-i2c: Move st,syscfg-fmp definition to top level

From: Rob Herring
Date: Wed Jan 19 2022 - 12:44:23 EST


It is preferred to define all properties in the main schema and leave
if/then/else schemas to just be further constraints on properties.

Rework the schema to use be more specific for each cell. Previously,
multiple entries of 3 cells each was allowed.
