    kconfig: adjust NR_CPUS defaults
    
    Discussion of a RISC-V change revealed that for PPC and RISC-V we don't
    really set any default, but rather rely on internals of kconfig picking
    the lowest of the permitted values in such a case. Let's make this
    explicit, requiring architectures that mean to permit SMP by default to
    explicitly record some sensible value here.
    
    Leverage the adjustment to the "1" case to simplify all subsequent ones.
