    ioapic/icu: Rework PIC selection code
    
    - In the early stage, before I/O APIC is detected and setup, ICU controls
      interrupts, so all IDT entries should be set to ICU's intr code.
    - Switch to I/O APIC only after ICU is completely disconnected, i.e. after
      IMCR is set and LINT0 is masked.
