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 at secretlab.ca>

    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.
