Setting the kernel version (PV) using gitpkgv.
But I notices several problems, so this is not working yet:

gitpkgv uses --exact-match in git describe, so the tags are only
used if the used rev is tagged but the documented versioning scheme
with tagname and offset is not working.

When --exact-match is removed the version comes out correctly as
5.4.23-70-gHASH but during the initial fetch after a clean the version
is 'None' and the gitpkgv is not called.

When fetch is done with 5.4.23... there was also a problem with the
recioe-sysroot-native.
