media: atmel: atmel-isc: create callback for DPC submodule product specific 

The DPC submodule is a part of the atmel-isc pipeline, and stands for
Defective Pixel Correction. Its purpose is to detect defective pixels and
correct them if possible with the help of adjacent pixels.
Create a product specific callback for initializing the DPC submodule
of the pipeline.
For sama5d2 product, this module does not exist, thus this function is a noop.
