gpio: switch drivers to use new callback
This switches all GPIO and pin control drivers with irqchips that were using .startup() and .shutdown() callbacks to lock GPIO lines for IRQ usage over to using the .request_resources() and .release_resources() callbacks just introduced into the irqchip vtable.
