This driver requires of_get_display_timing() from
CONFIG_VIDEOMODE_HELPERS but does not select it. If no other driver
selects it, there will be a failure from the linker if the driver is
built in or modpost if it is a module.
ERROR: modpost: "of_get_display_timing" [drivers/gpu/drm/sitronix/st7571-i2c.ko] undefined!
Select CONFIG_VIDEOMODE_HELPERS to resolve the build failure.
