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: arm/chacha-neon - add missing counter increment
-
-commit fd16931a2f518a32753920ff20895e5cf04c8ff1 upstream.
-
-Commit 86cd97ec4b943af3 ("crypto: arm/chacha-neon - optimize for non-block
-size multiples") refactored the chacha block handling in the glue code in
-a way that may result in the counter increment to be omitted when calling
-chacha_block_xor_neon() to process a full block. This violates the skcipher
-API, which requires that the output IV is suitable for handling more input
-as long as the preceding input has been presented in round multiples of the
-block size. Also, the same code is exposed via the chacha library interface
-whose callers may actually rely on this increment to occur even for final
-blocks that are smaller than the chacha block size.
-
-So increment the counter after calling chacha_block_xor_neon().
