kernel: remove support for kernel 4.19

We use 5.4 on all targets by default, and 4.19 has never been released
in a stable version. There is no reason to keep it.

-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.
