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] bridge: multicast to unicast
-MIME-Version: 1.0
-Content-Type: text/plain; charset=UTF-8
-Content-Transfer-Encoding: 8bit
-
-Implements an optional, per bridge port flag and feature to deliver
-multicast packets to any host on the according port via unicast
-individually. This is done by copying the packet per host and
-changing the multicast destination MAC to a unicast one accordingly.
-
-multicast-to-unicast works on top of the multicast snooping feature of
-the bridge. Which means unicast copies are only delivered to hosts which
-are interested in it and signalized this via IGMP/MLD reports
-previously.
-
-This feature is intended for interface types which have a more reliable
-and/or efficient way to deliver unicast packets than broadcast ones
-(e.g. wifi).
-
-However, it should only be enabled on interfaces where no IGMPv2/MLDv1
-report suppression takes place. This feature is disabled by default.
-
-The initial patch and idea is from Felix Fietkau.
