    [mips*el/loongson-3] Set NR_CPUS=16 to allow for Loongson 3B2000
    
    The Loongson 3B2000 has 4 cores and can apparently be used in a 4-way
    configuration, for 16 CPUs.
    
    I don't think the current configuration will run on a 3B2000, but this
    should avoid an ABI break if we address that.
