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.

+# This script is meant to be used to mark failing hydra builds as broken in the meta attrs
+# To use the script, you should pass the list of failing attrs as arguments to the script.
+#
+# Example: `cat failing-attrs | xargs ./pkgs/common-updater/scripts/mark-broken`
+#
+# Generating a list of failing attrs: (this should be improved at a later date)
+#   - Go to the most recent hydra evaluation with all builds completed
+#   - Select the "builds still failing" tab
+#   - Highlight and select all packages, should be prefixed with `nixpkgs.`
+#   - Use regex and editor foo to leave only the attr names
+#   - Use the above example command to then execute the script
+#
+# OTHER NOTES:
+#   - The `denyFileList` and `denyAttrList` will likely need to be updated slightly
+#     to align with the conventions used in nixpkgs at execution time
+#   - Any attrs which failed for any reason will be written to `failed-marks.txt`.
+#     Those attrs will likely need manual attention as disablement will likely be conditional.
