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: caam - use mapped_{src,dst}_nents for descriptor
-MIME-Version: 1.0
-Content-Type: text/plain; charset=UTF-8
-Content-Transfer-Encoding: 8bit
-
-The mapped_{src,dst}_nents _returned_ from the dma_map_sg
-call (which could be less than src/dst_nents) have to be
-used to generate the job descriptors.
