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



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.
