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] netfilter: nf_flow_table: clean up and fix dst handling
-
-dst handling in the code is inconsistent and possibly wrong. In my test,
-skb_dst(skb) holds the dst entry after routing but before NAT, so the
-code could possibly return the same dst entry for both directions of a
-connection.
-Additionally, there was some confusion over the dst entry vs the address
-passed as parameter to rt_nexthop/rt6_nexthop.
-
-Do an explicit dst lookup for both ends of the connection and always use
-the source address for it. When running the IP hook, use the dst entry
-for the opposite direction for determining the route.
