[ Upstream commit 80cc8c0d09e6bab3bd016ddaccd0570cadbe1891 ]
Similar to other variants, the LTK050H3148W wants to run in video mode when displaying data. So far only the Synopsis DSI driver was using this panel and it is always switching to video mode, independent of this flag being set.
Other DSI drivers might handle this differently, so add the flag.
