Introduce a new domain for wakeup capable GPIOs. The domain can be requested using the bus token DOMAIN_BUS_WAKEUP. In the following patches, we will specify PDC as the wakeup-parent for the TLMM GPIO irqchip. Requesting a wakeup GPIO will setup the GPIO and the corresponding PDC interrupt as its parent.
