gpiolib: override irq_enable/disable
When using the gpiolib irqchip helpers install irq_enable/disable hooks for the irqchip to ensure that gpiolib knows when the irq is enabled or disabled, allowing drivers to disable the irq and then use it as an output pin, and later switch the direction to input and re-enable the irq.
