irqchip/gic: Kill the xlate method We are now left with only two use models for the GIC driver: - Via a firmware interface, which mandates a hierarchical domain, and the use of the 'translate' method - The legacy platforms, which assume irq==hwirq, hence not using the 'xlate' method. The logical conclusion is that we can now nuke the 'xlate' method altogether.
