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: dsa: move switchdev event implementation under the same
- switch/case statement
-
-We'll need to start listening to SWITCHDEV_FDB_{ADD,DEL}_TO_DEVICE
-events even for interfaces where dsa_slave_dev_check returns false, so
-we need that check inside the switch-case statement for SWITCHDEV_FDB_*.
-
-This movement also avoids a useless allocation / free of switchdev_work
-on the untreated "default event" case.
