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/curve25519 - add arch-specific key generation
- function
-
-commit 84faa307249b341f6ad8de3e1869d77a65e26669 upstream.
-
-Somehow this was forgotten when Zinc was being split into oddly shaped
-pieces, resulting in linker errors. The x86_64 glue has a specific key
-generation implementation, but the Arm one does not. However, it can
-still receive the NEON speedups by calling the ordinary DH function
-using the base point.
