drm/bridge: cdns-dsi: Don't fail on MIPI_DSI_MODE_VIDEO_BURST 



While the cdns-dsi does not support DSI burst mode, the burst mode is
essentially DSI event mode with more versatile clocking and timings.
Thus cdns-dsi doesn't need to fail if the DSI peripheral driver requests
MIPI_DSI_MODE_VIDEO_BURST.

In my particular use case, this allows the use of ti-sn65dsi83 driver.
