MSM DSI host driver actually parses "data-lanes" in DT and compare it with the number of DSI lanes the bridge driver sets for mipi_dsi_device. So we need to always specify "data-lanes" for the DSI host output. As of now, "data-lanes" is added to ti-sn65dsi86 dts fragment, but missing in parade-ps8640 dts fragment, which requires a fixup. Since we'll do 4-lane DSI regardless of which bridge chip is used, instead of adding "data-lanes" to parade-ps8640 dts fragment, let's just move "data-lanes" from the bridge dts to sc7180-trogdor.dtsi.
