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: lower the default congestion thresholds
-
-The congestion thresholds need to be set in such a way that:
-    a) the threshold is high enough so that frames aren't dropped
-    unnecessarily
-    b) the threshold is low enough so that the latency isn't too big
-
-The current thresholds are set too high. In forwarding scenarios, the
-latency is too large and frames are dropped on ingress due to a lack of
-buffers.
