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.

+      '' The name Pies (pronounced "p-yes") stands for Program Invocation and
+         Execution Supervisor.  This utility starts and controls execution of
+         external programs, called components.  Each component is a
+         stand-alone program, which is executed in the foreground.  Upon
+         startup, pies reads the list of components from its configuration
+         file, starts them, and remains in the background, controlling their
+         execution.  If any of the components terminates, the default action
+         of Pies is to restart it.  However, it can also be programmed to
+         perform a variety of another actions such as, e.g., sending mail
+         notifications to the system administrator, invoking another external
+         program, etc.
+
+         Pies can be used for a wide variety of tasks.  Its most obious use
+         is to put in backgound a program which normally cannot detach itself
+         from the controlling terminal, such as, e.g., minicom.  It can
+         launch and control components of some complex system, such as
+         Jabberd or MeTA1 (and it offers much more control over them than the
+         native utilities).  Finally, it can replace the inetd utility!
