    loongarch64: set PREEMPT_NONE as default preemption model
    
    Loongarch64 currently uses the PREEMPT_VOLUNTARY model, which is not
    aligned with OpenWrt's default. Switch to PREEMPT_NONE for consistency with
    OpenWrt's default configuration. Preemption model selection is now
    available via menuconfig for further customization.
