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] net_sched/codel: do not defer queue length update
-
-When codel wants to drop last packet in ->dequeue() it cannot call
-qdisc_tree_reduce_backlog() right away - it will notify parent qdisc
-about zero qlen and HTB/HFSC will deactivate class. The same class will
-be deactivated second time by caller of ->dequeue(). Currently codel and
-fq_codel defer update. This triggers warning in HFSC when it's qlen != 0
-but there is no active classes.
-
-This patch update parent queue length immediately: just temporary increase
-qlen around qdisc_tree_reduce_backlog() to prevent first class deactivation
-if we have skb to return.
-
-This might open another problem in HFSC - now operation peek could fail and
-deactivate parent class.
