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] net: mscc: ocelot: don't hardcode the number of the CPU port
-
-VSC7514 is a 10-port switch with 2 extra "CPU ports" (targets in the
-queuing subsystem for terminating traffic locally).
-
-There are 2 issues with hardcoding the CPU port as #10:
-- It is not clear which snippets of the code are configuring something
-  for one of the CPU ports, and which snippets are just doing something
-  related to the number of physical ports.
-- Actually any physical port can act as a CPU port connected to an
-  external CPU (in addition to the local CPU). This is called NPI mode
-  (Node Processor Interface) and is the way that the 6-port VSC9959
-  (Felix) switch is integrated inside NXP LS1028A (the "local management
-  CPU" functionality is not used there).
-
-This patch makes it clear that the ocelot_bridge_stp_state_set function
-operates on the CPU port (by making it an implicit member of the
-bridging domain), and at the same time adds logic for the NPI port (aka
-a physical port) to play the role of a CPU port (it shouldn't be part of
-bridge_fwd_mask, as it's not explicitly enslaved to a bridge).
