irqchip: mips-cpu: Introduce IPI IRQ domain support
Introduce support for registering an IPI IRQ domain suitable for use by
systems using the MIPS MT (multithreading) ASE within a single core.
This will allow for such systems to be supported generically, without
the current kludge of IPI code split between the MIPS arch & the malta
board support code.
