[PATCH v2 24/30] media: atmel: atmel-isc: move the formats list into product specific code

[Eugen Hristev <eugen.hristev@microchip.com>]

The list of input and output formats has to be product specific.
Move this list into the product specific code.
Have pointers to these arrays inside the device struct.
