drm/panel: sharp-ls043t1le01: adjust mode settings

Browse Source 
[ Upstream commit dee23b2c9e3ff46d59c5d45e1436eceb878e7c9a ]

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.
