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] sdk_dpaa: ceetm: avoid double frees on error paths
-
-The stack calls the destroy() callback when a qdisc init() fails.
-We stop calling it ourselves and trust the stack do the cleanup.
