Oh I see, it exists already but it's only built into the tree for
microblaze, x86, and ppc.

There's a lot of stuff in there which is superfluous and will never
be used on sparc.

Everything in there except the new of_pci_find_child_device() function
will be never ever used on sparc and therefore dead code.
