kernel: delete Linux 5.4 config and patches

As the upcoming release will be based on Linux 5.10 only, remove all

There were no targets still actively using Linux 5.4.

-Subject: [PATCH] wireguard: peer: put frequently used members above cache
- lines

-commit 5a0598695634a6bb4126818902dd9140cd9df8b6 upstream.
-
-The is_dead boolean is checked for every single packet, while the
-internal_id member is used basically only for pr_debug messages. So it
-makes sense to hoist up is_dead into some space formerly unused by a
-struct hole, while demoting internal_api to below the lowest struct
-cache line.
