The driver already takes the version into account in several places, but this approach won't scale well for features that are found in different versions. Introduce a new mechanism using a features bitmask in the rkisp1_info structure to indicate which features the ISP support. The first feature bit tells if the ISP has an internal CSI-2 receiver, which is not available in all ISP versions.
