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: socket: remove bogus __be32 annotation
-
-commit 7f57bd8dc22de35ddd895294aa554003e4f19a72 upstream.
-
-The endpoint->src_if4 has nothing to do with fixed-endian numbers; remove
-the bogus annotation.
-
-This was introduced in
-https://git.zx2c4.com/wireguard-monolithic-historical/commit?id=14e7d0a499a676ec55176c0de2f9fcbd34074a82
-in the historical WireGuard repo because the old code used to
-zero-initialize multiple members as follows:
-
-    endpoint->src4.s_addr = endpoint->src_if4 = fl.saddr = 0;
-
-Because fl.saddr is fixed-endian and an assignment returns a value with the
-type of its left operand, this meant that sparse detected an assignment
-between values of different endianness.
-
-Since then, this assignment was already split up into separate statements;
-just the cast survived.
