[PATCH v3 5/7] pipeline: rpi: Track which ISP output is configured for a stream

[Naushir Patuck]

Add a ispIndex field to CropParams that is used to track
which ISP output (0/1) will be used for a given stream during
configuration.

Tracking this information is required for an upcoming change where crop
rectangles can be specified for each configured stream. Currently, the
value is fixed to 0.
