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. Signed-off-by: Daniel Golle <daniel@makrotopia.org>

-Subject: [PATCH 20/33] MIPS: pci-ar724x: convert to OF
-
-With the ath79 target getting converted to pure OF, we can drop all the
-platform data code and add the missing OF bits to the driver. We also add
-a irq domain for the PCI/e controllers cascade, thus making it usable from
-dts files.
