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] crypto: lib/chacha20poly1305 - use chacha20_crypt()
-
-commit 413808b71e6204b0cc1eeaa77960f7c3cd381d33 upstream.
-
-Use chacha20_crypt() instead of chacha_crypt(), since it's not really
-appropriate for users of the ChaCha library API to be passing the number
-of rounds as an argument.
