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.

+      mGBA is a new Game Boy Advance emulator written in C.
+
+      The project started in April 2013 with the goal of being fast enough to
+      run on lower end hardware than other emulators support, without
+      sacrificing accuracy or portability. Even in the initial version, games
+      generally play without problems. It is loosely based on the previous
+      GBA.js emulator, although very little of GBA.js can still be seen in mGBA.
+
+      Other goals include accurate enough emulation to provide a development
+      environment for homebrew software, a good workflow for tool-assist
+      runners, and a modern feature set for emulators that older emulators may
+      not support.
