irqchip: crossbar: Convert dra7 crossbar to stacked domains
Support for the TI crossbar used on the DRA7 family of chips is implemented as an ugly hack on the side of the GIC. Converting it to stacked domains makes it slightly more palatable, as it results in a cleanup. Unfortunately, as the DT bindings failed to acknowledge the fact that this is actually yet another interrupt controller (the third, actually), we have yet another breakage. Oh well.
