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.
