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: blake2s - x86_64 SIMD implementation
-
-commit ed0356eda153f6a95649e11feb7b07083caf9e20 upstream.
-
-These implementations from Samuel Neves support AVX and AVX-512VL.
-Originally this used AVX-512F, but Skylake thermal throttling made
-AVX-512VL more attractive and possible to do with negligable difference.
