It is found on many allwinner soc that there is a low probability that the interrupt status cannot be read in sunxi_pinctrl_irq_handler. This will cause the interrupt status of a gpio bank to always be active on gic, preventing gic from responding to other spi interrupts correctly.

So we should call the chained_irq_* each time enter sunxi_pinctrl_irq_handler().

Patch applied.
