irqdomain: Remove powerpc dependency from debugfs file

The debugfs code is really generic for all platforms.  This patch removes the
powerpc-specific directory reference and makes it available to all
architectures.

This option will show the mapping relationship between hardware irq
numbers and virtual irq numbers. The mapping is exposed via debugfs
in the file powerpc/virq_mapping.
If you don't know what this means you don't need it.
