Display lists support up to 8 bodies but we currently use a single one. To support preparing display lists for large look-up tables, add support for multi-body display lists.

The vsp1_dl_list_put() function expects to be called with the display list manager lock held. This assumption is correct for calls from within the vsp1_dl.c file, but not for the external calls. Fix it by taking the lock inside the function and providing an unlocked version for the internal callers.

The subdev s_stream operation is abused as a generic way to setup modules at every frame. Move the code out to a new VSP1 entity configure operation. Most modules now have an empty s_stream operation that can be removed. The only exception is the WPF module that needs to perform hardware configuration when stopping the stream. The code can be simplified accordingly as we know that that operation never fails.

Display lists can operate in header or headerless mode. The headerless mode is only available on WPF0, to be used with the display engine. All other WPF instances can only use display lists in header mode. Implement support for header mode to prepare for display list usage on WPFs other than 0.

The RPF source memory pointers need to be offset to take the crop rectangle into account. Offsets are computed in the RPF stream start, which can happen (when using the DRM pipeline) after calling the RPF .set_memory() operation that programs the buffer addresses. The .set_memory() operation tries to guard against the problem by skipping programming of the registers when the module isn't streaming. This will however only protect the first use of an RPF in a DRM pipeline, as in all subsequent uses the module streaming flag will be set and the .set_memory() operation will use potentially incorrect offsets. Fix this by allowing the caller to decide whether to program the hardware immediately or just cache the addresses. While at it refactor the memory set code and create a new vsp1_rwpf_set_memory() that cache addresses and calls the .set_memory() operation to apply them to the hardware. As a side effect the driver now writes all three DMA address registers regardless of the number of planes, and initializes unused addresses to zero.

The datasheet clearly states that all but a few registers can't be modified when the device is running. Programming the intensity parameters in the control set handler is thus prohibited. Program it when starting the module instead. This requires storing the intensity value internally as the module can be started from the frame completion interrupt handler, and accessing control values requires taking a mutex.

The DRM pipeline, as it runs in automatic restart mode, never sees the pipeline state set to VSP1_PIPELINE_STOPPING or VSP1_PIPELINE_STOPPED when running the frame end interrupt handler. We can thus skip the checks various checks in the handler and return immediately. Similarly the DRM frame end handler calls vsp1_pipeline_run() unnecessarily, as the state there is never VSP1_PIPELINE_STOPPED. Remove the function call and the frame end handler is it's now empty.
