Moving to kernel dev-4.13

[Joel Stanley]

Hello OpenBMCers,

I've pushed a new branch to the OpenBMC kernel repository. It's called
dev-4.13, and is based on the latest stable release from the 4.13
branch (4.13.5).

There are currently 40 patches on top of the upstream release that
include the patches sent upstream since 4.13 was released. In
addition, there is the new Aspeed clk driver that is out on the
upstream lists for review.

If you wish to have your non-upstreamed patches added to this tree,
please send them to the list with the [PATCH linux dev-4.13] tag.

If you have any questions or concerns then please use this thread to
kick off a discussion.

Cheers,

Joel
