kernel: delete Linux 5.4 config and patches

As the upcoming release will be based on Linux 5.10 only, remove all
kernel configuration as well as patches for Linux 5.4.
There were no targets still actively using Linux 5.4.

-Subject: [PATCH] wireguard: selftests: test multiple parallel streams
-
-commit d5a49aa6c3e264a93a7d08485d66e346be0969dd upstream.
-
-In order to test ndo_start_xmit being called in parallel, explicitly add
-separate tests, which should all run on different cores. This should
-help tease out bugs associated with queueing up packets from different
-cores in parallel. Currently, it hasn't found those types of bugs, but
-given future planned work, this is a useful regression to avoid.
-
-Fixes: e7096c131e51 ("net: WireGuard secure network tunnel")
