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] kbuild: add macro for controlling warnings to
- linux/compiler.h
-
-I have occasionally run into a situation where it would make sense to
-control a compiler warning from a source file rather than doing so from
-a Makefile using the $(cc-disable-warning, ...) or $(cc-option, ...)
-helpers.
-
-The approach here is similar to what glibc uses, using __diag() and
-related macros to encapsulate a _Pragma("GCC diagnostic ...") statement
-that gets turned into the respective "#pragma GCC diagnostic ..." by
-the preprocessor when the macro gets expanded.
-
-Like glibc, I also have an argument to pass the affected compiler
-version, but decided to actually evaluate that one. For now, this
-supports GCC_4_6, GCC_4_7, GCC_4_8, GCC_4_9, GCC_5, GCC_6, GCC_7,
-GCC_8 and GCC_9. Adding support for CLANG_5 and other interesting
-versions is straightforward here. GNU compilers starting with gcc-4.2
-could support it in principle, but "#pragma GCC diagnostic push"
-was only added in gcc-4.6, so it seems simpler to not deal with those
-at all. The same versions show a large number of warnings already,
-so it seems easier to just leave it at that and not do a more
-fine-grained control for them.
-
-The use cases I found so far include:
-
-- turning off the gcc-8 -Wattribute-alias warning inside of the
-  SYSCALL_DEFINEx() macro without having to do it globally.
-
-- Reducing the build time for a simple re-make after a change,
-  once we move the warnings from ./Makefile and
-  ./scripts/Makefile.extrawarn into linux/compiler.h
-
-- More control over the warnings based on other configurations,
-  using preprocessor syntax instead of Makefile syntax. This should make
-  it easier for the average developer to understand and change things.
-
-- Adding an easy way to turn the W=1 option on unconditionally
-  for a subdirectory or a specific file. This has been requested
-  by several developers in the past that want to have their subsystems
-  W=1 clean.
-
-- Integrating clang better into the build systems. Clang supports
-  more warnings than GCC, and we probably want to classify them
-  as default, W=1, W=2 etc, but there are cases in which the
-  warnings should be classified differently due to excessive false
-  positives from one or the other compiler.
-
-- Adding a way to turn the default warnings into errors (e.g. using
-  a new "make E=0" tag) while not also turning the W=1 warnings into
-  errors.
-
-This patch for now just adds the minimal infrastructure in order to
-do the first of the list above. As the #pragma GCC diagnostic
-takes precedence over command line options, the next step would be
-to convert a lot of the individual Makefiles that set nonstandard
-options to use __diag() instead.
-
-[paul.burton@mips.com:
-  - Rebase atop current master.
-  - Add __diag_GCC, or more generally __diag_<compiler>, abstraction to
-    avoid code outside of linux/compiler-gcc.h needing to duplicate
-    knowledge about different GCC versions.
-  - Add a comment argument to __diag_{ignore,warn,error} which isn't
-    used in the expansion of the macros but serves to push people to
-    document the reason for using them - per feedback from Kees Cook.
-  - Translate severity to GCC-specific pragmas in linux/compiler-gcc.h
-    rather than using GCC-specific in linux/compiler_types.h.
-  - Drop all but GCC 8 macros, since we only need to define macros for
-    versions that we need to introduce pragmas for, and as of this
-    series that's just GCC 8.
-  - Capitalize comments in linux/compiler-gcc.h to match the style of
-    the rest of the file.
-  - Line up macro definitions with tabs in linux/compiler-gcc.h.]
