If CONFIG_DRM_LVDS_ENCODER=y but CONFIG_DRM_KMS_HELPER=m,
build fails:

drivers/gpu/drm/bridge/lvds-encoder.o: In function `lvds_encoder_probe':
lvds-encoder.c:(.text+0x155): undefined reference to `devm_drm_panel_bridge_add'

Fixes: dbb58bfd9ae6 drm/bridge: ("Fix lvds-encoder since the panel_bridge rework.")
