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: accept frames on RX even if larger than MTU
-
-Documentation/networking/netdevices.txt mentions that interfaces must
-be able to receive frames at least the size of the configured MTU. The
-behavior for received frames larger than the MTU is unspecified. We have
-been dropping these frames in software. Remove this behavior and accept
-them.
