drm/panel: sharp-ls043t1le01: adjust mode settings
Using current settings causes panel flickering on APQ8074 dragonboard.
Adjust panel settings to follow the vendor-provided mode. This also
enables MIPI_DSI_MODE_VIDEO_SYNC_PULSE, which is also specified by the
vendor dtsi for the mentioned dragonboard.
