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] dpaa2-eth: Add congestion group taildrop
-
-The increase in number of ingress frame queues means we now risk
-depleting the buffer pool before the FQ taildrop kicks in.
-
-Congestion group taildrop allows us to control the number of frames
-that can accumulate on a group of Rx frame queues belonging to the
-same traffic class.
-
-This setting coexists with the frame queue based taildrop: whichever
-limit gets hit first triggers the frame drop.
