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.

+      Splint is a tool for statically checking C programs for security
+      vulnerabilities and coding mistakes.  With minimal effort, Splint
+      can be used as a better lint.  If additional effort is invested
+      adding annotations to programs, Splint can perform stronger
+      checking than can be done by any standard lint.
