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] soc: fsl: dpio: enable qbman CENA portal memory access
-
-Once we enable the cacheable portal memory, we need to do
-cache flush for enqueue, vdq, buffer release, and management
-commands, as well as invalidate and prefetch for the valid bit
-of management command response and next index of dqrr.
