drivers/clock_control: stm32: clock_control_on: check cc-sub_system

Browse source 
This commit adds a check for the validity of the "sub_system" param in
clock_control_on.

While for clock_control_off there was a check if the clock_subsytem
parameter is in range of STM32_PERIPH_BUS_MIN and STM32_PERIPH_BUS_MAX
this check was missing for clock_control_on.
