gpiolib: Fix GPIO chip IRQ initialization restriction

Browse source

[ Upstream commit 8c00914e54 ]

In case of gpio-regmap, IRQ chip is added by regmap-irq and associated with
GPIO chip by gpiochip_irqchip_add_domain(). The initialization flag was not
added in gpiochip_irqchip_add_domain(), causing gpiochip_to_irq() to return
-EPROBE_DEFER.
