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: create a helper for changing the port MTU
-
-Since in an NPI/DSA setup, not all ports will have the same MTU, we need
-to make sure the watermarks for pause frames and/or tail dropping logic
-that existed in the driver is still coherent for the new MTU values.
-
-We need to do this because the NPI (aka external CPU) port needs an
-increased MTU for the DSA tag. This will be done in a future patch.
