    Subject[PATCH v6 06/11] irqchip: mips-cpu: Convert to simple domain
    Date
    The old code is using legacy domain to setup irq_domain for CPU interrupts
    which requires irq_desc to be preallocated.

    However, when MIPS_CPU_IRQ_BASE >= 16, irq_desc for CPU IRQs may end up
    unallocated and lead to incorrect behavior.

    Thus we convert the legacy domain to simple domain which can allocate irq_desc
    during initialization.
