This oops is caused by a wrong chip_data and it is because plic_irq_unmask

get another irq_data with the same irq_data->irq if it is hierarchy.
In this case, it will get irq_data of sifive_gpio_irqchip instead of
plic_chip so that it will get a wrong chip_data and then the wrong lmask
of it to cause this oops.

Applied to irq/irqchip-next, thanks!

I agree. I'm assuming that's for Marc, but LMK if you guys want me to take it.
