irqchip/gic: Kill the xlate method

Browse source 
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.
