[Buildroot] [git commit master 1/1] u-boot: add Marvell u-boot.kwb support

[Peter Korsgaard]

commit: http://git.buildroot.net/buildroot/commit/?id=3cd5174ed796400a9566c0ea52f3551cba52bfe0
branch: http://git.buildroot.net/buildroot/commit/?id=refs/heads/master

Marvell boards like the sheevaplug needs a special .kwb image format,
so add an option for it similar to how we handle zImage/uImage/..
for the kernel.
