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 625/660] net: sfp: control TX_DISABLE and phy only from main
- state machine
-
-We initialise TX_DISABLE when the sfp cage is probed, and then
-maintain its state in the main state machine.  However, the module
-state machine:
-- negates it when detecting a newly inserted module when it's already
-  guaranteed to be negated.
-- negates it when the module is removed, but the main state machine
-  will do this anyway.
-
-Make TX_DISABLE entirely controlled by the main state machine.
-
-The main state machine also probes the module for a PHY, and removes
-the PHY when the the module is removed.  Hence, removing the PHY in
-sfp_sm_module_remove() is also redundant, and is a left-over from
-when we tried to probe for the PHY from the module state machine.
