Currently we are trying to enable/disable the clk of irq's gpio bank when
unmask/mask irq. But the kernel's "lazy disable approach" will skip masking
irq when the irq chip doesn't support irq_disable ops.
So we may hit this case:
irq_enable-> enable clk
irq_disable-> noop
irq_enable-> enable clk again
irq_disable-> noop
