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.

+      Unclutter hides your X mouse cursor when you do not need it, to prevent
+      it from getting in the way. You have only to move the mouse to restore
+      the mouse cursor. Unclutter is very useful in tiling wm's where you do
+      not need the mouse often.
+
+      Just run it from your .bash_profile like that:
+
+          unclutter -idle 1 &
+    '';
