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] staging: dpaa2-mac: add link up/down events for dpmac
-
-Fix a limitation that affects the networking behavior when the user
-issues ifconfig down/up on a DPNI and the link remains down.
-The actual problem was that the mac driver was not aware of the
-dpni link change event. Now, the event is sent by firmware and
-phylib state machine is manipulated conveniently.
