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.
