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 621/660] net: sfp: handle module remove outside state machine
-
-Removing a module resets the module state machine back to its initial
-state.  Rather than explicitly handling this in every state, handle it
-early on outside of the state machine.
