[PATCH v2 25/30] media: atmel: atmel-isc: create an adapt pipeline callback for product specific

[Eugen Hristev]

Once the pipeline is set in the base code, create a callback that will adapt
the ISC pipeline to each product.
Create the adapt_pipeline callback that will be used in this fashion.

Changes in v2:
- addded function prototype to avoid warning with W=1
