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 out fdb operations into abstract
- implementations
-
-To be able to implement a DSA front-end over ocelot_fdb_add,
-ocelot_fdb_del, ocelot_fdb_dump, these need to have a simple function
-prototype that is independent of struct net_device, netlink skb, etc.
-
-So rename the ndo ops of the ocelot driver into
-ocelot_port_fdb_{add,del,dump}, and have them all call the abstract
-implementations. At the same time, refactor ocelot_port_fdb_do_dump into
-a function whose prototype is compatible with dsa_fdb_dump_cb_t, so that
-the do_dump implementations can live together and be called by the
-ocelot_fdb_dump through a function pointer.
