nouveau: add coherent BO attribute
Add a flag allowing Nouveau to specify that an object should be coherent at allocation time. This is required for some class of objects like fences which are randomly-accessed by both the CPU and GPU. This flag instructs the kernel driver to make sure the object remains coherent even on architectures for which coherency is not guaranteed by the bus.
