Some system control registers need to be clocked, so the registers can
be accessed. Add an optional clock.

No. Add clocks to specific bindings using syscon. If you have a node 
with only 'syscon', then that should be fixed.

Hi Rob,

Thanks for reviewing, so I'll
- add it to Documentation/devicetree/bindings/arm/stm32/stm32-syscon.txt
- send a v2 with this change.

Best regards,
Fabrice
