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: adjust MTU on the CPU port in NPI mode
-
-When using the NPI port, the DSA tag is passed through Ethernet, so the
-switch's MAC needs to accept it as it comes from the DSA master. Increase
-the MTU on the external CPU port to account for the length of the
-injection header.
-
-Without this patch, MTU-sized frames are dropped by the switch's CPU
-port on xmit, which is especially obvious in TCP sessions.
