irqdomain: Add bus token DOMAIN_BUS_WAKEUP
A single controller can handle normal interrupts and wake-up interrupts independently, with a different numbering space. It is thus crucial to allow the driver for such a controller discriminate between the two.
A simple way to do so is to tag the wake-up irqdomain with a "bus token" that indicates the wake-up domain. This slightly abuses the notion of bus, but also radically simplifies the design of such a driver. Between two evils, we choose the least damaging.
