Subject: [PATCH] irqchip: mips-cpu: Remove eoi operation
The eoi opreation in mips_cpu_irq_controller caused chained_irq_enter
falsely consider CPU IP interrupt as a FastEOI type IRQ. So the interrupt
won't be masked during in handler. Which might lead to spurious interrupt.
Thus we simply remove eoi operation for mips_cpu_irq_controller,
