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: separate the implementation of switch
- reset
-
-The Felix switch has a different reset procedure, so a function pointer
-needs to be created and added to the ocelot_ops structure.
-
-The reset procedure has been moved into ocelot_init.
