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 01/10] tcp: tsq: add tsq_flags / tsq_enum
-
-This is a cleanup, to ease code review of following patches.
-
-Old 'enum tsq_flags' is renamed, and a new enumeration is added
-with the flags used in cmpxchg() operations as opposed to
-single bit operations.
