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: chacha20poly1305 - prevent integer overflow on large
- input
-
-commit c9cc0517bba9f0213f1e55172feceb99e5512daf upstream.
-
-This code assigns src_len (size_t) to sl (int), which causes problems
-when src_len is very large. Probably nobody in the kernel should be
-passing this much data to chacha20poly1305 all in one go anyway, so I
-don't think we need to change the algorithm or introduce larger types
-or anything. But we should at least error out early in this case and
-print a warning so that we get reports if this does happen and can look
-into why anybody is possibly passing it that much data or if they're
-accidently passing -1 or similar.
