gpio: rcar: Add Runtime PM handling for interrupts
The R-Car GPIO driver handles Runtime PM for requested GPIOs only.
When using a GPIO purely as an interrupt source, no Runtime PM handling
is done, and the GPIO module's clock may not be enabled.
To fix this:
- Add .irq_request_resources() and .irq_release_resources() callbacks
to handle Runtime PM when an interrupt is requested,
- Add irq_bus_lock() and sync_unlock() callbacks to handle Runtime PM
when e.g. disabling/enabling an interrupt, or configuring the
interrupt type.
