This patch adds 'irq' directory into the root debugfs and 
virq_mapping for getting the virq to
irq host's hwirq mapping list.

Minor nit. Should we be creating a 'powerpc' directory first, and
putting the 'irq' file under that? Otherwise we risk clashing with some
generic code that creates a file called 'irq' in debugfs.

Or put the whole IRQ tree under sysfs generically...
