Subject: [PATCH] gpio: drop broken to_gpio_irq_chip() helper

Drop the broken to_gpio_irq_chip() container_of() helper, which would
break the build for anyone who tries to use it.

Specifically, struct gpio_irq_chip only holds a pointer to a struct
irq_chip so using container_of() on an irq-chip pointer makes no sense.

Fixes: da80ff81a8f5 ("gpio: Move irqchip into struct gpio_irq_chip")
