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.

+      Coccinelle is a program matching and transformation engine which
+      provides the language SmPL (Semantic Patch Language) for
+      specifying desired matches and transformations in C code.
+      Coccinelle was initially targeted towards performing collateral
+      evolutions in Linux.  Such evolutions comprise the changes that
+      are needed in client code in response to evolutions in library
+      APIs, and may include modifications such as renaming a function,
+      adding a function argument whose value is somehow
+      context-dependent, and reorganizing a data structure.  Beyond
+      collateral evolutions, Coccinelle is successfully used (by us
+      and others) for finding and fixing bugs in systems code.
