The vsp1_dl library allows to program a display list and feed it continuously to the VSP2. As an alternative operation mode, the library allows to program the VSP2 in 'single shot' mode, where a display list is submitted to the VSP on request only. Currently the 'single shot' mode is only available when the VSP2 is controlled by userspace, while it works in continuous mode when driven by DRM, as frames have to be submitted to the display continuously. For the VSPX use case, where there is no uapi support, we should however work in single-shot mode as the ISP driver programs the VSPX on request. Initialize the display lists in single shot mode in case the VSP1 is controlled by userspace or in case the pipeline features an IIF entity, as in the VSPX case.
