Subject[PATCH v3 06/10] 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 being 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.
