When CONFIG_GENERIC_HARDIRQS_NO_DEPRECATED is defined, struct irq_desc
no longer contains a ->chip member pointing to the corresponding struct
irq_chip, leading to the following build error:
drivers/gpio/langwell_gpio.c: In function 'lnw_irq_handler':
drivers/gpio/langwell_gpio.c:210: error: 'struct irq_desc' has no member named 'chip'
drivers/gpio/langwell_gpio.c:211: error: 'struct irq_desc' has no member named 'chip'
Fix this up by using get_irq_desc_chip(desc) to get the irq_chip,
instead of trying to get it via desc->chip directly.
