uboot: (firmwareOdroidC2/C4) don't invoke patch tool, use patches = [] instead

https://github.com/NixOS/nixpkgs/blob/master/pkgs/stdenv/generic/setup.sh#L948
this can do it nicely.

+      Bikeshed is a pre-processor for spec documents, turning a source document
+      (containing only the actual spec content, plus several shorthands for linking
+      to terms and other things) into a final spec document, with appropriate boilerplate,
+      bibliography, indexes, etc all filled in. It's used on specs for CSS
+      and many other W3C working groups, WHATWG, the C++ standards committee, and elsewhere!
