Add support for sending MIPI DSI command packets from the host to a peripheral. This is required for panels that need configuration before they accept video data. Also for long reads to work properly, set DCS maximum return packet size to the value of the DMA buffer size. Based on Renesas Linux kernel v5.10 repos [1].
