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>
