linux-yocto: introduce 5.2 recipes

Introducing the 5.2 linux-yocto reference kernels. 5.0 is EOL and will
be removed, leaving 4.19 (LTS) and 5.2 as the reference kernels.

This has been build/boot tested on all qemu architectures for
core-image-kernel-dev, and graphics tesed via core-image-sato. No
blocking issues have been found.
