linux-yocto: introduce 5.4 recipes

This creates recipes for the v5.4/* branches of the linux-yocto
reference kernel.

preempt-rt, yaffs2, aufs5 and reference board specific patches are
part of these branches. All major architectures: x86,x86-64,ARM,
ARM64,ppc,mips and mips64 have been feature tested against this
reference.

5.4 is a LTS release, and as such will receive -stable updates
for the duration of upstream korg support.
