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: device: do not generate ICMP for non-IP packets
-
-commit 99fff5264e7ab06f45b0ad60243475be0a8d0559 upstream.
-
-If skb->protocol doesn't match the actual skb->data header, it's
-probably not a good idea to pass it off to icmp{,v6}_ndo_send, which is
-expecting to reply to a valid IP packet. So this commit has that early
-mismatch case jump to a later error label.

-Fixes: e7096c131e51 ("net: WireGuard secure network tunnel")
