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: split assignment of the cpu port into a
- separate function
-
-Now that the places that configure routing destinations for the CPU port
-have been marked as such, allow callers to specify their own CPU port
-that is different than ocelot->num_phys_ports. A user will be the Felix
-DSA driver, where the CPU port is one of the physical ports (NPI mode).
