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 13/18] usb: host: fotg2: add silicon clock handling
-
-When used in a system with software-controlled silicon clocks,
-the FOTG210 needs to grab, prepare and enable the clock.
-
-This is needed on for example the Cortina Gemini, where the
-platform will by default gate off the clock unless the
-peripheral (in this case the USB driver) grabs and enables
-the clock.
-
-If there is no clock available on the platform, we live
-without it. Make sure to percolate probe deferrals.
-

----
-ChangeLog v1->v2:
-- Handle probe deferrals on the clock controller, no matter
-  how unlikely they are.
-- Send the patch to get Gemini USB rolling and try to get some
-  stuff upstream, this patch should be fine on its own.
