[media] media: define Media Controller API when CONFIG_MEDIA_CONTROLLER enabled
Change to define Media Controller API when CONFIG_MEDIA_CONTROLLER
is enabled. Define stubs for CONFIG_MEDIA_CONTROLLER disabled case.
This will help avoid drivers needing to enclose Media Controller
code within ifdef CONFIG_MEDIA_CONTROLLER block.
