The SH Mobile LCDC driver exposes overlay configuration via sysfs.
These attributes depend on FB_DEVICE and cause build failures when
FB_DEVICE=n.
Wrap all overlay sysfs attribute definitions and group registrations
within CONFIG_FB_DEVICE. When FB_DEVICE is disabled, the driver still
loads but without sysfs entries.
