    arm: cxd56xx: Fix nvic settings for SMP
    
    Summary:
    - I noticed that ostest sometimes stops with DEBUGASSERT
    - Finally I found a bug that cpu1 can not disable interrupt
    - This commit initializes nvic to fix this bug
    
    Impact:
    - Only affects cxd56 in SMP mode
    
    Testing:
    - spresense:smp and spresense:wifi_smp with DEBUG_ASSERTIONS=y
