Laurent Pinchart dd856d924b drm: rcar-du: Fix rcar_du_of_init() stub
The rcar_du_of_init() function is supposed to be defined as a stub when
CONFIG_DRM_RCAR_LVDS is disabled as the rcar_du_of.c file isn't compiled
in that case. However, a bug in the configuration option check makes it
a stub when CONFIG_DRM_RCAR_LVDS=m as well, which prevents legacy DTs
from being fixed at boot time. Fix the configuration option check by
using IS_ENABLED.
