From: Manikanta Guntupalli <manikanta.guntupa...@amd.com> commit f5691439353783ef114876849c70d2a641e09498 upstream.
Make the struct irq_chip const and flag it as IRQCHIP_IMMUTABLE, call gpiochip_disable_irq() in the .irq_mask() callback and gpiochip_enable_irq() in the .irq_unmask() callback to fix "gpio gpiochip1: (zynqmp_gpio): not an immutable chip" warning.
