x86: Increase the default NR_CPUS to 128. We have newer systems which have more than 64 CPUs, and users often complain some cpus can't be waken up when play with Xen. Certainly, MAX_PHYS_CPUS option also can support more CPUs, but it is still inconvenient for them, so change the default value to 128.
