media: atomisp: Add target validation to atomisp_subdev_set_selection()
As the 2 comments in the function already say both the sink and the source
pads only support setting the selection for 1 target:
/* Only crop target supported on sink pad. */
/* Only compose target is supported on source pads. */
Validate that the passed in target actually matches these expectations.
