meta-yocto/linux-yocto-3.0: update branch mappings for new tools

Updates to the kern-tools to be more flexible and support multiple
upstream repository formats means that KMACHINE should really only
map to a machine and that KBRANCH should specify branch information.

To adapt to this change, we split the hardware reference boards into
KMACHINE and KBRANCH mappings.
