Adding linux-sh (arch/sh) to linux-next

[Rich Felker]

Hi Stephen,

Can you please add the linux-sh tree's for-next branch to be pulled
for linux-next?

	git://git.libc.org/linux-sh for-next

Let me know if anything's wrong with how it's set up. I'm new to
linux-next (and still fairly new to arch maintainership) so apologies
if I missed anything. I do plan to move the tree to kernel.org,
hopefully soon, but I'm still waiting on people who promised to sign
my keys so for the time being it's still on libc.org.
