gpio: thunderx: Convert to immutable irq_chip
Convert the driver to immutable irq-chip with a bit of intuition. Whereas in most cases we put the gpiochip_[enable|disable]_irq() calls in the .irq_mask() and .irq_unmask() callbacks, here we need to put them in the .irq_enable() and .irq_disable() callbacks, as this driver uses both .irq_mask() and .irq_mask_ack().
