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.

+      PLY is an implementation of lex and yacc parsing tools for Python.
+      In a nutshell, PLY is nothing more than a straightforward lex/yacc
+      implementation.  Here is a list of its essential features: It's
+      implemented entirely in Python; It uses LR-parsing which is
+      reasonably efficient and well suited for larger grammars; PLY
+      provides most of the standard lex/yacc features including support for
+      empty productions, precedence rules, error recovery, and support for
+      ambiguous grammars; PLY is straightforward to use and provides very
+      extensive error checking; PLY doesn't try to do anything more or less
+      than provide the basic lex/yacc functionality.  In other words, it's
+      not a large parsing framework or a component of some larger system.
