media: vsp1: wpf: Add writeback support Add support for the writeback feature of the WPF, to enable capturing frames at the WPF output for display pipelines. To enable writeback the vsp1_rwpf structure mem field must be set to the address of the writeback buffer and the writeback field set to true before the WPF .configure_stream() and .configure_partition() are called. The WPF will enable writeback in the display list for a single frame, and writeback will then be automatically disabled.
