remoteproc: don't allow modular build
Remoteproc started using dma_declare_coherent_memory recently, which is a bad idea from drivers, and the maintainers agreed to fix that. But until that is fixed only allow building the driver built in so that we can remove the dma_declare_coherent_memory export and prevent other drivers from "accidentally" using it like remoteproc. Note that the driver would also leak the declared coherent memory on unload if it actually was built as a module at the moment.
