The VSP2-DL instance (present in the H3 ES2.0 and M3-N SoCs) has two LIF instances. Adapt the driver infrastructure to support multiple LIFs. Support for multiple display pipelines will be added separately. The change to the entity routing table removes the ability to connect the LIF output to the HGO or HGT histogram generators. This feature is only available on Gen2 hardware, isn't supported by the rest of the driver, and has no known use case, so this isn't an issue.
