treewide: remove files for building 5.10 kernel

All targets are bumped to 5.15. Remove the old 5.10 patches, configs
and files using:

  find target/linux -iname '*-5.10' -exec rm -r {} \;

Further, remove the 5.10 include.

-Subject: [PATCH 2/2] 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().
