linux-yocto: split meta data from kernel repository

The linux-yocto tree has always been a combined set of kernel changes
and configuration (meta) data carried in a single tree. While this
format is effective at keeping kernel configuration and source
modifications synchronized, it isn't always obvious to developers on
how to manipulate the meta data versus the source.

With this change, we remove the meta data processing from the
kernel-yocto class and use the external meta-data repository that
has always been used to seed the linux-yocto meta branch.

After this change, linux-yocto can no longer process combined trees,
and is simplified as a result.
