    Revert "lantiq: xway: kernel: enable SMP support"
    
    Enabling SMP on the xway target results in two issues:
    
    * some danube chipset-based devices fail on boot,
    * on devices based on the arx100 chipset, enabling smp
    results in a degradation of NAT performance.
    
    After these two issues are fixed, SMP can be re-enabled.
    
    This reverts commit 084c20f6c54180f2dc6b3efc1c5ba9b62afbaf26.
    
    Fixes: #13934
    Fixes: #14283
