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.
