drm/panel: ltk050h3146w: Set burst mode for ltk050h3148w

Browse Source 
The ltk050h3148w variant expects the horizontal component lane byte clock
cycle(lbcc) to be calculated using lane_mbps (burst mode) instead of the
pixel clock.
Using the pixel clock rate by default for this calculation was introduced
in commit ac87d23694 ("drm/bridge: synopsys: dw-mipi-dsi: Use pixel clock
rate to calculate lbcc") and starting from commit 93e82bb4de
("drm/bridge: synopsys: dw-mipi-dsi: Fix hcomponent lbcc for burst mode")
only panels that support burst mode can keep using the lane_mbps. So add
MIPI_DSI_MODE_VIDEO_BURST as part of the mode_flags for the dsi host.
