Revert "build: scripts/config - update to kconfig-v5.6"

This reverts commit dcf3e63a35d05e7e5103819c0f17195bfafe9baa.

The kconfig update requires further testing and refinement until it can
remain in tree. Main problems are:

 - Recursive deps are now fatal instead of a warning
 - Previously legal syntax now leads to hard failures
 - It fails all package builds since multiple days

The updated kconfig implementation needs to cope with the current status
quo in the various package feeds before we can reconsider it for master.

It is not desirable that single broken packages can hard-fail the entire
build pipeline.
