Some devices treat two independent physical DSI panels as a single logical panel from the CRTC's perspective. However, two separate DSI hosts are still required to drive the panels individually.
Introduce a `dual_panel` flag to the `mipi_dsi_device` struct. This allows a panel driver to inform the DSI host that it is part of a dual-panel setup, enabling the host to coordinate both physical displays as one.
