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] MLK-19801-1 crypto: caam - add tag functionality
-MIME-Version: 1.0
-Content-Type: text/plain; charset=UTF-8
-Content-Transfer-Encoding: 8bit
-
-Add functions to tag an object with metadata(configuration).
-
-It is possible to:
- - create metadata:
-	- init_tag_object_header
-	- init_blackey_conf
-	- set_tag_object_conf
- - retrieve metadata:
-	- get_tag_object_conf
-	- get_blackey_conf
-
-The API expects an object to be a space a memory
-with an address and a size.
-
-The implementation of the tag is currently exposed
-but users shouldn't access it directly, they should
-use the functions provided.
