machine struct - specify max_cpus at the per machine level (Jes Sorensen)
Introduce a max_cpus per-machine variable, allowing individual boards to limit it's number of CPUs. Check requested number of CPUs in setup code and exit if it exceeds the supported number for the machine. This also renders the static MAX_CPUS check obsolete, so remove this from vl.c.
