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. Signed-off-by: Daniel Golle <daniel@makrotopia.org>

-Subject: [PATCH] regmap: make LZO cache optional
-
-Commit 2cbbb579bcbe3 ("regmap: Add the LZO cache support") added support
-for LZO compression in regcache, but there were never any users added
-afterwards. Since LZO support itself has its own size, it currently is
-rather a deoptimization.
-
-So make it optional by introducing a symbol that can be selected by
-drivers wanting to make use of it.
-
-Saves e.g. ~46 kB on MIPS (size of LZO support + regcache LZO code).
-
-Signed-off-by: Jonas Gorski <jonas.gorski@gmail.com>
----
-I tried using google to find any users (even out-of-tree ones), but at
-best I found a single driver submission that was switched to RBTREE in
-subsequent resubmissions (MFD_SMSC).
-
-One could maybe also just drop the code because of no users for 5 years,
-but that would be up to the maintainer(s) to decide.
