PowerPC actually uses CONFIG_PPC, so this doesn't work. However, this
might be better: I've compile tested it on powerpc, but I don't have
microblaze or sparc xcompilers right now. Also, probably word-wrapped
since I'm pasting it into my mailer, but I wanted to keep this within
the thread. I'll repost "for real" first thing tomorrow morning.

commit 302d02a46c67938cf4ef310fec90734cb38acabe
Author: Grant Likely <grant.likely@xxxxxxxxxxxx>
Date: Mon Apr 27 21:54:35 2009 -0600
of: make of_(un)register_platform_driver common code.
Some drivers using of_register_platform_driver() wrapper break on sparc
because the wrapper isn't in the header file. This patch moves it from
Microblaze and PowerPC implementations and makes it common code.
