linux-yocto: introduce 5.8 reference kernel

Browse Source 
Add the next set of "versioned" linux-yocto recipes that can be
used to build v5.8 upstream (v5.8/base) or 5.8 with some emedded
specific features (v5.8/standard/*).

Note: along with the new 5.8 content, the recipes have a tweaked
licence checksum, which The needs to be updated to account for kernel
commit 74835c7db0322b [COPYING: state that all contributions really
are covered by this file].

These have been built and booted for all supported qemu architectures.

(From OE-Core rev: 18edf84ec6cfcc137602f89ddc024d1fe1dcf03a)
