video: stm32: dcmipp: remove const for clock structs

Remove the const attribute of the struct stm32_pclken
in the struct stm32_dcmipp_config since this leads to
warnings due to losing the const pointer when calling
the clock_control functions.
Casts done when calling the clock_control_on functions
were also wrong hence fix this.
