misc: microchip: pci1xxxx: Resolve kernel panic during GPIO IRQ handling
Resolve kernel panic caused by improper handling of IRQs while
accessing GPIO values. This is done by replacing generic_handle_irq with
handle_nested_irq.
Fixes: 1f4d8ae231f4 ("misc: microchip: pci1xxxx: Add gpio irq handler and irq helper functions irq_ack, irq_mask, irq_unmask and irq_set_type of irq_chip.")
