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.
