linux-yocto: remove or adjust to _ in branch names

The existing 2.6.34 kernel tree uses _ where poky typically
uses -. This is a historical artifact, since working with
gnu Make and shells means avoiding - is wise. The opposite
is true in Yocto.

To avoid using the _ reserved character wherever possible
we can simply remove it from the branch names in the
new 2.6.37 kernel, but to keep the content stable in the
0.9 2.6.34 kernel, we map _ to - for the purposes of
packaging.

To further faciliate this switch, the branch names no
longer need to be shortened in the KMACHINE mappings, but
can be fully specified and the tools/processing adapt as
required. This gives us the flexibility to map multiple
boards to a single branch for building.
