irqchip/renesas-intc-irqpin: Use wakeup_path i.s.o. explicit clock handling
Since commit 705bc96c2c15313c ("irqchip: renesas-intc-irqpin: Add
minimal runtime PM support"), when an IRQ is used for wakeup, the INTC
block's module clock (if exists) is manually kept running during system
suspend, to make sure the device stays active.
However, this explicit clock handling is merely a workaround for a
failure to properly communicate wakeup information to the device core.
Instead, set the device's power.wakeup_path field, to indicate this
device is part of the wakeup path. Depending on the PM Domain's
active_wakeup configuration, the genpd core code will keep the device
enabled (and the clock running) during system suspend when needed.
This allows for the removal of all explicit clock handling code from the
driver.
