[PATCH] powerpc: Do not ignore arch/powerpc/include

[Junio C Hamano <gitster@pobox.com>]

Back when .gitignore file was added to arch/powerpc/ in 06f2138 ([POWERPC]
Add files build to .gitignore, 2006-11-26), there indeed was nothing
tracked in the ignored hierarchy and ignoring everything made sense.  But
we have very many tracked files there these days, and having a higher
level .gitignore that ignores everything is asking for future troubles..

This should have been part of b8b572e (powerpc: Move include files to
arch/powerpc/include/asm, 2008-08-01).

  I looked at this a bit more and now I know this was not intended.
