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: avoid double unlikely() notation when using
- IS_ERR()
-
-commit 30ac4e2f54ec067b7b9ca0db27e75681581378d6 upstream.
-
-The definition of IS_ERR() already applies the unlikely() notation
-when checking the error status of the passed pointer. For this
-reason there is no need to have the same notation outside of
-IS_ERR() itself.
-
-Clean up code by removing redundant notation.
