media: davinci: make function arguments const
Make the function arguments of functions vpfe_{register/unregister}_ccdc_device const as the pointer dev does not modify the fields of the structure it points to. Also, declare the variable ccdc_dev const as it points to the same structure as dev but it does not modify the fields as well.
