The new RePaper driver uses the thermal subsystem, and fails to link
when it is built-in but thermal is a loadable module:
drivers/gpu/drm/tinydrm/repaper.o: In function `repaper_probe':
repaper.c:(.text+0x540): undefined reference to `thermal_zone_get_zone_by_name'
drivers/gpu/drm/tinydrm/repaper.o: In function `repaper_fb_dirty':
repaper.c:(.text+0xff4): undefined reference to `thermal_zone_get_temp'
This adds another Kconfig dependency to prevent the broken configuration,
forcing repaper to be a module too.
