The patches "OMAP: DSS2: enable VDDS_DSI when using DPI" (8a2cfea8cc) by Tomi Valkeinen and "ARM: omap: fix oops in drivers/video/omap2/dss/dpi.c" (4041071571) by Russell King had introduced these checks. As it is evident from these patches a dependency exists for some DSS pins on VDDS_DSI which is better shown by dss feature FEAT_DPI_USES_VDDS_DSI.
