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] arc add OWRTDTB section
-
-This change allows OpenWRT to patch resulting kernel binary with
-external .dtb.
-
-That allows us to re-use exactky the same vmlinux on different boards
-given its ARC core configurations match (at least cache line sizes etc).
-
-""patch-dtb" searches for ASCII "OWRTDTB:" strign and copies external
-.dtb right after it, keeping the string in place.
