drm: rockchip: select DRM_GEM_CMA_HELPER The rockchip drm driver started using drm_gem_cma_vm_ops, but that might not be part of the kernel, causing the link to fail: drivers/gpu/built-in.o:(.data+0xb234): undefined reference to `drm_gem_cma_vm_ops' This adds a Kconfig 'select' statement to enable it like the other user do.
