kernel: drop everything not on kernel version 4.14

 * Remove testing patches for kernel version 4.19
 * remove targets ar7, ixp4xx, orion
Those targets are still on kernel 4.9, patches for 4.14 were not ready
in time. They may be readded once people prepare and test patches for
kernel 4.14.

-Subject: [PATCH] ubifs: Drop softlimit and delta fields from struct ubifs_wbuf
-MIME-Version: 1.0
-Content-Type: text/plain; charset=UTF-8
-Content-Transfer-Encoding: 8bit
-
-Values of these fields are set during init and never modified. They are
-used (read) in a single function only. There isn't really any reason to
-keep them in a struct. It only makes struct just a bit bigger without
-any visible gain.
