    arm64: Move intr_pic_init_secondary earlier
    
    This may have been called after intr_irq_shuffle. For most interrupt
    controllers this appears to be safe, however for the GICv5 we need to
    read a per-CPU ID register before we can assign interrupts to a given
    CPU.
    
    Fix the race by moving intr_pic_init_secondary earlier in the boot,
    after devices have been enumerated and before the interrupts are moved
    to their assigned CPUs.
