The wording "configure dsi slave channel" doesn't really tell you
exactly what this *is*; in fact, it's more like a description of the SW
than the HW (DT is supposed to describe HW).

You probably want something like "phandle to a 2nd DSI channel; useful
as a slave channel when driving a panel which needs 2 DSI links".
