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.

+
+      To use the driver adjust your configuration.nix file:

+          drivers = [ pkgs.epson-escpr ];
+        };

+      To setup a wireless printer, enable Avahi which provides

+      hostname resolvable:
+        services.avahi = {
+          enable = true;
