drm: Link CMA framebuffer helpers into KMS helper library 

Linking the CMA framebuffer helpers into a CMA helper library in
commit 4b2b5e142f ("drm: Move GEM memory managers into modules")
results in linker errors:

  arm-linux-gnueabihf-ld: drivers/gpu/drm/drm_fb_cma_helper.o: \
	  in function `drm_fb_cma_get_gem_obj': \
	  drivers/gpu/drm/drm_fb_cma_helper.c:46: undefined reference \
	  to `drm_gem_fb_get_obj'
  arm-linux-gnueabihf-ld: drivers/gpu/drm/drm_fb_cma_helper.c:46: \
	  undefined reference to `drm_gem_fb_get_obj'
  arm-linux-gnueabihf-ld: drivers/gpu/drm/drm_fb_cma_helper.c:46: \

  arm-linux-gnueabihf-ld: drivers/gpu/drm/drm_fb_cma_helper.o: in \
	  function `drm_fb_cma_sync_non_coherent': \
	  drivers/gpu/drm/drm_fb_cma_helper.c:133: undefined reference \

  arm-linux-gnueabihf-ld: drivers/gpu/drm/drm_fb_cma_helper.c:135: \
	  undefined reference to `drm_atomic_helper_damage_iter_next'

Link the CMA framebuffer helpers into the KMS helper library to
fix the problem.
