New location of powerpc git tree

[Benjamin Herrenschmidt]

Hi folks !

I've moved the powerpc git tree back to kernel.org. The URL should be
back to normal for users:

git://git.kernel.org/pub/scm/linux/kernel/git/benh/powerpc.git

I've only uploaded the next and merge branches for now (merge is stale
btw, it's just there to avoid breaking scripts).

Note: Ignore the "linux-powerpc.git" tree that's next to that one, it's
a mistake and I haven't manage to delete it just yet...

Cheers,
Ben.
