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.

+# zsh-git-prompt -- Informative git prompt for zsh
+#
+# Usage: to enable this plugin for all users, you could
+# add it to configuration.nix like this:
+#
+#   programs.zsh.interactiveShellInit = ''
+#     source ${pkgs.zsh-git-prompt}/share/zsh-git-prompt/zshrc.sh
+#   '';
+#
+# Or you can install it globally but only enable it in individual
+# users' ~/.zshrc files:
+#
+#   source /run/current-system/sw/share/zsh-git-prompt/zshrc.sh
+#
+# Or if installed locally:
+#
+#   source ~/.nix-profile/share/zsh-git-prompt/zshrc.sh
+#
+# Either way, you then have to set a prompt that incorporates
+# git_super_status, for example:
+#
+#   PROMPT='%B%m%~%b$(git_super_status) %# '
+#
+# More details are in share/doc/zsh-git-prompt/README.md, once
+# installed.
