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: break apart ocelot_vlan_port_apply
-
-This patch transforms the ocelot_vlan_port_apply function ("apply
-what?") into 3 standalone functions:
-
-- ocelot_port_vlan_filtering
-- ocelot_port_set_native_vlan
-- ocelot_port_set_pvid
-
-These functions have a prototype that is better aligned to the DSA API.
-
-The function also had some static initialization (TPID, drop frames with
-multicast source MAC) which was not being changed from any place, so
-that was just moved to ocelot_probe_port (one of the 6 callers of
-ocelot_vlan_port_apply).
