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. Signed-off-by: Daniel Golle <daniel@makrotopia.org> (cherry picked from commit 3a14580411adfb75f9a44eded9f41245b9e44606)

-Date: Mon, 13 Nov 2017 17:26:13 +0200
-Subject: [PATCH] dpaa2-eth: Add CEETM qdisc support
-
-Features include:
-- dual rate shaping support
-- per-channel shaping and classification
-- strict / weighted scheduling among num_tc classes
-- TD enabled for configured class queues
-- prio class (leaf) firmware statistics support
-- weights normalized based on max
-- tc filters based classification
-
-Only 1 CEETM ch supported, only channel shaping supported.
