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.
