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] mm: rename __page_frag functions to __page_frag_cache, drop
- order from drain
-
-This patch does two things.
-
-First it goes through and renames the __page_frag prefixed functions to
-__page_frag_cache so that we can be clear that we are draining or
-refilling the cache, not the frags themselves.
-
-Second we drop the order parameter from __page_frag_cache_drain since we
-don't actually need to pass it since all fragments are either order 0 or
-must be a compound page.
