Subject: [PATCH v2 09/30] media: atmel: atmel-isc: extract CBC submodule config into separate function

The CBC submodule should be initialized in the product specific driver
as it's product specific. Other products can implement it differently

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