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 1/1] Allow class-e address assignment in ifconfig and early
- boot
-
-While the linux kernel became mostly "class-e clean" a decade ago,
-and most distributions long ago switched to the iproute2 suite
-of utilities, which allow class-e (240.0.0.0/4) address assignment,
-distributions relying on busybox, toybox and other forms of
-ifconfig cannot assign class-e addresses without this kernel patch.
-
-With this patch, also, a boot command line on these addresses is feasible:
-(ip=248.0.1.2::248.0.1.1:255.255.255.0).
-
-While CIDR has been obsolete for 2 decades, and a survey of all the
-userspace open source code in the world shows most IN_whatever macros
-are also obsolete... rather than obsolete CIDR from this ioctl entirely,
-this patch merely enables class-e assignment, sanely.
-
-H/T to Vince Fuller and his original patch here:
