Jeffy Chen d468289a02 pinctrl: rockchip: add irq_enable & irq_disable ops
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
