[PATCH v2 2/2] qemu-options.hx: Document hmat-lb and hmat-cache order |

To simplify internal implementation the hmat-cache parsing code
expects hmat-lb to be already parsed. This means, that hmat-lb
arguments must come before hmat-cache. Document this restriction
so that management applications can follow it.
