dt-bindings: clock: convert stm32 rcc bindings to json-schema

The patch converts st,stm32-rcc.txt to the JSON schema, but it does more
than that. The old bindings, in fact, only covered the stm32f{4,7}
platforms and not the stm32h7. Therefore, to avoid patch submission tests
failing, it was necessary to add the corresponding compatible (i. e.
st,stm32h743-rcc) and specify that, in this case, 3 are the clocks instead
of the 2 required for the stm32f{4,7} platforms.
Additionally, the old bindings made no mention of the st,syscfg property,
which is used by both the stm32f{4,7} and the stm32h7 platforms.

The patch also fixes the files referencing to the old st,stm32-rcc.txt.
