x86: dtb: Add irq domain abstraction
The here introduced irq_domain abstraction represents a generic irq controller. It is a subset of powerpc's irq_host which is going to be renamed to irq_domain and then become generic. This implementation will be removed once it is generic. The xlate callback is resposible to parse irq informations like irq type and number and returns the hardware irq number which is reported by the hardware as active.
