videolink@1 makes the description of the CSI-2 rx board-specific.  Would it be
possible to keep the description of the SoC nodes board-agnostic to ease reuse
of the SoC description in multiple board DTs?

Would this be as simple as replacing &imx074 with a generic well-known name
defined in the board part of the DT?
