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: stop transmitting frames when the CQ is
- congested
-
-When the egress CQ is congested, drop the frames instead of enqueueing
-them. This is more efficient than enqueueing and receiving them back on
-the ERN queue.
-
-We also can't stop the netdev queues because that would affect all the CQs
-and would hinder prioritization.
