The YLM-LBV0345001H-V2 panel is a display panel used in the recent
revision of Anbernic RG35XX Plus, a handheld gaming device from Anbernic.
It is 3.45 inches in size (diagonally) with a resolution of 640x480.
It has the same interface (pins and connector) as WL-355608-A8, the panel
of the former revision of RG35XX Plus, but they differ on its
init-sequence. So add entry for the new panel.
