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.
