[PATCH] drm: Kconfig: Let all DRM_GEM_CMA_HELPER related macros depend on HAVE_DMA_ATTRS

[Chen Gang S <gang.chen@sunrus.com.cn>]

DRM_GEM_CMA_HELPER is depend on HAVE_DMA_ATTRS, or it will break the
building. The related error (with allmodconfig under xtensa):

    CC [M]  drivers/gpu/drm/drm_gem_cma_helper.o
