When no other driver selects CONFIG_VIDEOMODE_HELPERS but
CONFIG_DRM_CDNS_DSI is enabled, there is a linker or modpost error:
ERROR: modpost: "drm_display_mode_to_videomode"
[drivers/gpu/drm/bridge/cadence/cdns-dsi.ko] undefined!
Select VIDEOMODE_HELPERS to ensure that this helper function is
available to the driver.
Fixes: ce4bc5ca7c1d ("drm/bridge: cdns-dsi: Use video mode and clean up
cdns_dsi_mode2cfg()")
