Mark lantiq and omap as source only

[Paul Spooren]

Hi all,

I haven’t seen much progress happening regarding bringing the targets lantiq or omap to Kernel 5.15. That fact is currently the last blocker for branching another release.

Instead of postponing another release I’d like to mark both targets as source-only and do the 23.05 branch, starting with a RC0. If either of the two targets are fixed within the RC phase, they should be re-added, as discussed during the last meeting.

I’d value your feedback.

Sunshine,
Paul
