Subject: [PATCH 3/4] gpio: lpc18xx: select GPIOLIB_IRQCHIP

From: Peng Fan <peng.fan@....com>

This driver uses gpiochip_irq_reqres() and gpiochip_irq_relres() which
are only built with GPIOLIB_IRQCHIP=y. Add the missing Kconfig select.

Fixes: 289e42df1358 ("gpio: lpc18xx: Make irq_chip immutable")
