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: use -ffunction-sections, -fdata-sections and --gc-sections
-
-In combination with kernel symbol export stripping this significantly reduces
-the kernel image size. Used on both ARM and MIPS architectures.
