linux-yocto: introduce 4.14 recipes

This commit makes the 4.14 kernel available for use with the
Yocto configuration fragments and qemu* BSPs.

It has been tested for x86,arm,mips and powerpc against the
lsb, core* and glibc/mulsc test matrix.

This will serve as the LTS kernel in master, with others being
removed in subsequent commits.
